Cobra King F6+ driver: The best the industry has to offer?



Is the “best” driver the one that offers the most drastic adjustability? If so, Cobra’s new King F6+ may have a case as the industry leader, according to claims from the company.

The current obsession with adjustability in driver design is a puzzle for equipment engineers. How do they lower center of gravity to make the ball launch higher with less spin and raise moment of inertia to increase forgiveness… while simultaneously adding more and more adjustable features? According to Tom Olsavsky, vice president of R&D at Cobra, the company’s new King F6+ and King F6+ Pro drivers ($399) take an industry-leading step in the right direction. The trick? Carbon fiber.


Thanks to an 18-gram sliding weight housed in a carbon-fiber track (Cobra calls it a CarbonTrac), the F6+ offers the most drastic changes in front-to-back center of gravity (CG) adjustability — 6 millimeters front to back and 600 rpm of spin — and has the lowest CG of any adjustable driver on the market, according to Cobra.

For comparison, TaylorMade claims its M1 T-track system affects spin by 300 rpm when changing CG from front-to-back.

Related: Cobra’s King LTD driver, which boasts a “zero CG.”


The F6+ driver’s predecessor, the Fly-Z+, offered “FlipZone” adjustability, which let golfers move CG forward and backward. But a front setting and a back setting were the only two options. The F6+’s sliding weight track offers nine different CG options, and most importantly, Cobra was able to significantly lower CG, thus raising moment of inertia (MOI).

By building the track’s foundation out of 100 percent carbon fiber, Cobra was able reduce the weight of the structure by 8 grams compared to an all-titanium construction. The crown of the driver is also made from carbon fiber, a structure that the company says is 12 grams lighter than its titanium equivalent.


The F6+’s body is made from Ti 811, a material that’s lighter and stronger than the titanium used in the Fly-Z+, saving 6 grams in total. A new Speed Channel helps save 1.5-2 grams on the club face and is 10 to 15 percent better on off-center hits, according to Cobra.


The new Cobra F6+ drivers are available in four colors, and orange will be available for custom order, and the Turbulent/Gecko will be available on March 15.

What the F6+ driver doesn’t do, however, is allow golfers to move CG toward the heel or toe like a few other drivers in the market. Does that matter? Well, to a player who wants to tweak their draw or fade, it could be a problem.


Cobra’s solution? The company’s MyFly hosel, also specially designed to save weight, allows golfers to adjust loft and lie angle with eight different positions including three draw-biased settings, which make the driver more upright. Cobra’s new F6+ comes in an F6+ Pro head, too, which is essentially the same driver with less loft. It also has fade-biased lie angle settings instead of draw settings.

The loft and lie options between the King F6+ and F6+ Pro drivers


Something to keep in mind: When using the sliding weight track, you can also affect side-to-side trajectory. Sliding the weight forward will tend to make the driver more fade biased, while sliding it rearward will give the driver more draw bias.

The Cobra F6+ driver will be available at retail on Jan. 15, 2016.

    As someone who has gamed TM drivers since the 80’s, I wanted to offer my recent experience. I went to a demo day in Orlando a few months ago, and tried drivers from all the top manufacturers. As a golfer who tend to come in steep on the ball, having lots adjustability in the driver was very important. The F6+ and Mizuno JPX 900 w/speeder661, were the longest, but the consistency favored the Cobra. I bought the F6+ w/matrix black tie, at half the price of the JPX900, and have been driving the ball longer, straighter and with more consistency finding the fairway. I settled on the weight all the way forward and the loft set to 10.5° draw setting. I couldn’t be happier. Next up will be replacing my TM 3 wood and rescue with the Cobra F7 rail.

    F6+ sliding weight design is horrible. The weight should be squared off so it can’t rotate while you are tightening. The screw head snapped off on mine while I was tightening it. Great head with great numbers but a horrible design on the sliding weight.

      Anthony: so true. Had to ship my driver back to Cobra (thanks Roger Dunn). Third time to move the sliding wt and it stripped? Couldn’t be tightened. And yes it moves while you are trying to tighten it. Ended up sticking with my Mizuno JPX-850

    I recently demoed this F6+ and I have hit the king Ltd also. I own the fly z and the m1 and the F6+ is an AMAZING driver!! First off I’m a 8 handicap right now with an average 100 mph swing speed. I like to hit a mid/high trajectory with a slight draw and my fly z gives me that with a 260 yard average drive. This F6 straight out of the bag I was hitting the ball 250 with a 14 mph head wind. I made a few adjustments and was getting over 20 yards further then with my fly z and the M1!! So I took out the king Ltd to compare and the F6+ won by only a few yards. Like I said I’m not a pro and don’t have the swing speed of one either, but these cobra drivers are just AWESOME!!

    I play the Fly Z+ woods and they are legit! Really feels like the ball explodes off the face. I am interested in trying these. Not sure if they will offer any gains for me over the Fly Z+ but we will see!

    So I wait till 11/13 to see/hit the King LTD and now I have to wait till 1/15/16 for the F6? They keep this up and I may save a lot of bucks ’cause I will just keep waiting for the next great one.

    Did I miss something usually I’m great with understanding equipment, but kinda confused on the whole F6+ vs. King LTD thing this year, I kinda feel like their is two options you could go for based on what you want in a driver since their is 4 models total. I don’t know if I’m confused the average golfer is definitely going to be.

      They’ll also have the LTD XL, the bonded, non-adjustable, lightweight shaft with off-set hosel look version for the slow swing speed people. So that’ll be 5 different heads in one sitting

      • Casey

        Jan 10, 2016 at 10:46 am

        They really have 3 different heads this year. The LTD and LTD Pro are the same head, but the Pro has less loft and it’s lie angle is more flat. Same thing for the King F6+ and King F6+ Pro. Then they have the F6.

    It’s another take on adjustability. For me, I like the Callaway GBB because I can slide the perimeter weighting to fade to account for my normal miss – a toe hit. Put the weight to fade, hit it towards toe and the weight expands the sweetspot towards the toe, giving me a gentle draw or straight ball flight when coupled with a “D” hosel setting.

    The point is all of this tech is great. Choose the tech that works for you.

        The Rogue may not be for everyone, but combined with the GBB Alpha DBD, it’s about as point-and-shoot perfect as any shaft/driver combo I’ve hit in the last fifteen years….

        I’m liking Rogue Silver 70x on my E8 Beta 3 wood and as soon as my M1 arrives, i’m sure i will enjoy it as well.

Wunder: I’ve hit THESE new drivers this year…and this is what I think



During this lockdown, I have done quite a few “Friday Q & A’s” on my IG, and one of the questions I get asked constantly is “have you hit this?” That, and “whaddya think?”

So, in the spirit of organizing my brain, it seemed like the right time to share what new drivers I have actually hit this year…and this is what I think.

Now, it needs to be said that there is a lot of new gear out there, but, to be honest, I’ve only actually hit a select few enough to actually build an opinion. “Enough” in this case is at least 20 balls. Some of these sticks I tested during our pre-launch preview with the OEMs, at the PGA show, a friend has one, or I actually have it in the bag.

Here we go.

TaylorMade SIM

Setup tested: SIM 9 @8.25 w/ Mitsubishi Chemical Kuro Kage XTS 70TX

LOOKS: The best way to describe how SIM looks behind the ball is “comfortable.” TaylorMade has always made drivers that just look correct. The lines are clean, the shape inspires playability, and I dig the paint job. They hit a home run with this one for sure.

FEEL: Best sound out there in my opinion. Heavy, dense, and if you get one dead-nuts center, it lets you know. The feel at contact is just as TaylorMade drivers have always done, center strikes feel like Thor’s hammer and mishits don’t kill your good vibes.

VS THE M5: I get asked this a lot. I loved the M5. Still do. To be honest the two drivers data wise were legit apples to apples. The only difference is my stock shot with M5 was a low spin straight ball and with SIM its a slight draw with a touch more spin and slightly lower launch. I prefer that.

OVERALL: In my opinion, the TaylorMade SIM is the cool kid in high school for 2020. Last year it was F9 followed closely by M5. TM knocked it outta the park on this one.

TaylorMade SIM Max

Setup tested: Sim Max 9 @8.25 w/ Mitsubishi Chemical Kuro Kage XTS 70TX

LOOKS: It has a bit more of a longer face at address, which makes the head appear shallow which inspires a bit more confidence to turn it over. That’s the main thing I noticed with MAX. Other than that its a tried and true TM shape.

FEEL: Like its sibling, it has a nice solid hit audibly at the impact. So, overall its apples to apples with SIM. However, due to the front weight missing on the MAX, the actual strike doesn’t feel AS meaty as SIM. Not a negative necessarily just something I noticed.

VS M6: Both of these sticks I launched a bit too high versus the weighted versions. That’s why they never got any serious consideration to actually put in play.

OVERALL: As a high launch, more forgiving option, it’s an ace.

Callaway Mavrik Sub Zero

Setup tested: Sub Zero 9 w/ Mitsubishi Chemical Tensei Blue AV 65TX

LOOKS: To my eyes, the newer versions of the Callaway drivers have looked a bit more compact than its competition. To me, this always looked “low spin” for whatever reason. The Mavrik has the same shape which is good.

FEEL: They really fixed the sound. The Epic Flash sounded like a pop can to me, and the Mavrik Sub Zero sounds like a sledgehammer. The good thing here is the sound now matches up with what the hit feels like. I think the Mavrik is the best feeling driver Callaway has made since Epic.

VS EPIC FLASH SZ: To me, a complete improvement on all fronts. Sound, feel, and performance for me were all substantially better. Now I must say that the Epic Flash Sub Zero was a great driver, I always got great numbers out of it, but the sound took me out of it. I’m sure there isn’t that much difference audibly between the two, but in this game, even something minor can represent so much. Sound to me is huge.

OVERALL: In all honestly, I haven’t given a Callaway driver a real hard look to actually put in the bag since Epic. The sound got louder wit Rogue and Epic Flash. The Mavrik SZ  however is a fantastic driver and will def get some more testing out of me.

Cobra SpeedZone

Setup tested: Cobra Speed Zone 9 @8.5 w/ Fujikura Ventus Black 7X

LOOKS: The F9 was a winner on all fronts. The only critique I had was optically it looked like the driver was a little too fade biased. The SZ with its milled in top line gives it softer look at address and for me, softer lines mean more workability, just what my eyes tell me.

FEEL: As with F9 and the earlier mentioned SIM, the Speed Zone sounds EXACTLY how a driver should sound. It has a very heavy hit audibly and that’s across the face. I love the sound of this driver.

VS F9: Apples to apples, it’s the same. Beyond the optics, it feels, sounds, and performs like the F9. Not a bad thing though, the F9 was the driver of 2019 in my opinion.

OVERALL: Nothing wrong with repeating an already awesome driver. SpeedZone will stand up to anything out there. If I’m being fair, I think F9 elevated things in 2019, and this year the competition caught up to it. Changes nothing about how good this driver is.

Cobra Speed Zone Xtreme

Setup tested: Cobra Speed Zone Xtreme 9 @8.5 w/ Fujikura Ventus Black 7X

LOOKS: Like the other drivers in this higher MOI category, it looks a little longer heel to toe.

FEEL: No different than the SpeedZone, sounds great, the impact is solid across the face, and even thin shots feel solid.

OVERALL: The Xtreme is the sleeper hit of 2020 and I’ve heard the fitters love this thing. It’s by far the easiest to hit and overall good time of any driver on this list. Is it longer? No. But is it Xtremely (no pun) playable and competitive? Hard yes. It’s a blast.

PXG Proto

Setup tested: PXG Proto 9 w/ Graphite Design Tour AD IZ 6 TX

LOOKS: Slick. Like all PXG gear, the look is there. The matte crown and elegant lines make it very pleasing optically. I also appreciate that although it’s designed to look high tech. The lines inspire playability, and who doesn’t love a driver that looks like a stealth bomber?

FEEL: I only hit about 20 balls with the PXG Proto in the short time I had with it, but, wow, did this thing surprise me. The sound oddly enough is a bit higher-pitched than the others on the list but for whatever reason, it’s not a distraction. It actually adds to the experience of the hit. I typically detest that, but this sound matched up with the solid hit I was getting. I’m not sure if this is the final version since its a limited tour proto but what is happening is definitely interesting.

VS GEN2: It’s just better. Feels better, sounds great, more playable across the face. The Gen2 did one thing better than everyone else, it destroyed spin. The problem I had was control. The PXG Proto is still low spin but with the new 4 weight system (no intel on the tech yet) seems to add quality launch to the low spin profile and puts the player in a situation where very few to any sacrifices are made.

OVERALL: I was a fan of Gen2. No doubt. But it never flat out beat M5, F9, or SIM. The Proto has elevated PXG’s driver game. I don’t think its a matter of whether or not the driver stands up with the irons, I believe PXG is on the right track to having a driver that eliminates any “yeah, but…” to the conversation. That’s a huge leap since Gen1. These guys are trending hard.

I hope this was helpful.

Should I move to heavier iron shafts? – GolfWRXers have their say



In our forums, our members have been discussing the strategy of moving to heavier shafts in irons. WRXer ‘Z1ggy16’ has been making swing changes lately, and the transition has been most challenging for his iron play. ‘Ziggy16’ says:

“Been making some swing changes lately, most notably working to really shallow my club into the downswing. I’m finding that I’m doing this well with my heavy wedge shafts and driver, but I’m struggling a bit in my irons. My strike pattern with my wedges is pretty good, but the irons are a bit all over. Driver is 80g raw, wedges are 132g raw, irons 120g raw. I don’t think I want to go any stiffer, but is there a chance I’ve “outgrown” this weight and need to move to something a bit heavier to help keep these feels going through my set? No idea what swing speed is at this point, but my 7i is normally a smooth/comfortable 175-180 for me.

I really like the feel of my Accra Tour Z Xtreme 475 and my S400’s in the GW-LW. I’m kind of leaning maybe soft stepping modus 120TX or X100’s.. Heck maybe even S200 straight in? Normally I’d just get a fitting, but with Rona still going around, I’m not than keen on it. 2020 is the year of the self fit for me. FWIW, I used modus 120TX 2xSS in my GW & SW last year and that was pretty good feeling. Perhaps a touch too soft… they seemed to really whip/bend hard when hitting from the rough on full swings.”

Our members discuss whether they feel a switch to heavier shafts in the irons will have the desired impact.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • Pepperturbo: “You’re not alone. Regardless of age, some of us swing better with heavier shafts. I went from 70g driver and 85g 3wd graphite shafts to 58g Ventus shaft in driver and 70g Ventus shaft in 4wd. In irons went from 130g X to 120g 6.0 PX steel shafts which lasted about fifteen years. Then last year made another downward weight change to Steelfiber (steel & graphite) 110g Stiff shafts, lightest I have ever played. Keep in mind as you transition, changing shaft weight is not the only answer. Increasing swing weight can make up for shaft weight. Though I really like them in 6-3i, not thrilled in SW-7i, so just ordered heavier Steelfiber i125g shafts for my PW-7i blades.”
  • Jeff58: “As someone who has gone through and continues to work on what sounds like a similar situation, your ideal iron shafts will likely change. Where they change to isn’t possible to predict with any degree of accuracy. Don’t change your current irons without knowing. It’s frustrating, expensive, and you won’t have any clubs while they’re being changed out. Instead, get a single club from dealsandsteals or similar and experiment with that. Also, the only relevant experience is outdoors under your actual turf conditions. Indoor and mat use can be grossly different.”
  • Red4282: “Just depends on your tempo and load and preferences tbh. My numbers are about identical to yours; I play 77g in the driver and 125 in the irons. I don’t think I could go lighter than 125.”
  • gvogel: “I have a set of hickory clubs. Of course, hickory shafts are darn heavy, maybe 150 grams or so. I probably hit straighter shots with the irons, and particularly hit better shots with the niblick (wedge). Driver and fairway woods, not so much. That might be a stupid insertion into an intelligent thread, but heavier goes straighter, lighter goes longer. You can go heavier, and it helps in transition, but don’t go too stiff.”
