Most golfers understand shafts are designated by flex… but what is often misunderstood is how shaft flex relates to other factors not often discussed including weight and profile.

In the video, I break down some simple things to consider when its comes to steel shafts — flex, weight and bend profile — as well as why you might fit into a flex you weren’t expecting.

    Hi Ryan,

    I have been building and repairing clubs since the late 80s, while working at Kings Forest Golf Course. Over the years i have been fortunate enough to be educated by Tim Wishon, Oakville Golf staff… One question that i have for You is how much do you think playability is affected by putting a heavier midsize grip on a set of irons when they were originally built wuth standard size grips? Do you think i should tip weight heads to bring the swingweight up the 3 points or leave status quo? My friend is an excellent player at Heron Point and he said he did not notice the lower SW when i regripped with midsize grips.

      Good Question Dave,

      Some players will notice the counter balanced effect of the heavier grips while many will not. By adding back more weight to the head to get the swing weight back you will also soften the shafts a bit. The proof is always in the pudding, and in the case of the added weight to the butt end if the players likes the performance dont worry about swing weight.

    i partially disagree with what he said, for amateur golfers, weight is important to prevent injuries, few years ago with a new set of clubs, shaft 120g i got epicondylitis, in just two months, a fitter friend of mine told me to go for graphite, while another fitter told me to go for 80g steel, i follow the suggestion, and with the 80g i never got epicondylitis again

    Great video! Question maybe you can answer this one. I’m playing regular, KBS C-Taper lites… my ball flight is very high, would like to bring it down as I play in Florida wind.. swing speed is pretty average. Would you suggest moving to graphite stiff???? Thx

      No the graphite would give a higher flight,lite shafts help get the ball airborne easy. Try a standard weight.

      The single biggest factor for ball flight is player dynamics. If the ball flight is too high maybe try bending your irons a bit strong first before trying a shaft change.
      Best advice is to always see a fitter.

    Reading about flex is one thing, best thing is to find a fitter or even a big store like PGA Superstore and just hit balls with different shafts in what ever head your interested in playing. Either work with scope or just your feelings and you will find some that feel right or feel completely wrong…you may be supersized how different shafts can feel/work for you….while playing the head you want to play…

    Great video! Could you do a video on CPM and how accurate shafts are in our clubs vs PROS clubs. More specifically, if you order a set of clubs from a major manufacturer, how accurate are the weight of club heads and weight and flex of shafts in what we have vs. what the pros have done. Some club fitters say they do a good job with quality control, others say its best to get CPM checked when clubs come in because a “stiff” shaft may be anywhere from 280 cpm to 305 cpm.

    Great information, something everyone leaves out when talking about flex. If a person wants a correct flex the weight has to be considered which is why Dyn. Gold had 5 flexes within a flex. The lightest of the dyn. golds were at 125 and the heaviest at 130 gr. which created different flex within a flex.

Forum Thread of the Day: GolfWRX Members love this golf bag



Today’s Forum Thread of the Day comes from Steelhead, who gave us a close look at his new Jones Trouper golf bag, and just like Steelhead, many of our members have been seriously impressed. The thread features plenty of in-hand photos of the new bags, and though many of our members have already dived in and ordered one for themselves, with Black Friday fast approaching, lots have been waiting for this week to get their hands on one.

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

  • Blink3665: “I’ve been lurking on this thread since it started.  With the Black Friday sale, I had to jump.  I grabbed a Navy bag with a few extra goodies (If I’m gonna pay for shipping I might as well grab a few other things, right?)”
  • slide13: “I’d say if you want to carry 14 clubs and don’t want a pretty tight fit, give the Trouper a try. I have the Utility, and it’s a cool bag, but I found it a super tight fit and not great with 14 clubs using midsize grips.  Maybe regular grips help.  I still like the bag, and I don’t mind using just 12 clubs or so which helps a little, but I’d still probably have found another solution if it was my main bag.”
  • Dubv23: “As soon as I pulled the trouper out of the box today I knew it was going to be my favorite bag.  It maintains a lot of the Utility styling but adds a lot of the features many wanted. The great thing is it does not make the bag that much bigger.  Its taller from the bottom of the opening to the top but not much wider and very well thought out. The material is different than past utilities, and I would assume it was to shed weight.  It has a hoofer like feel to the fabric but not so much to make it seem like it’s not a Jones bag. The opening is perfect and holds all 14 clubs perfect, the leg mechanism is smooth and much easier to release than the past, and the putter “well” is slick. “
  • mr.hicksta: “After seeing those additional pics, I’m even more excited about getting mine! Jones Golf doesn’t mess around with shipping, either. Mine looks like it’ll arrive on Monday, which is nice and quick from Oregon to Hawaii!”

Forum Thread of the Day: “Guys that shoot under par, what clubs do you use?”



Today’s Forum Thread of the Day comes from BiggEm, who asks those GolfWRX members that happen to break par consistently, what clubs they use. Driver and irons are the clubs in question which BiggEm is interested in hearing about, and as well as many posters submitting the clubs they use, an interesting debate regarding “arrow vs archer” has developed, as well as general playing tips from posters while out on the course.

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.

  • cm24: “5 years ago, When I was actually playing really well (for me), and I was in the +2 handicap range I was playing a set of Mizuno mp68 irons.  Sold those for AP2s and never have brought my game back.  I went thru 8 sets of irons over the three years after I sold the Mizunos and finally settled on a set of Srixon z965s.  I think those under par days are coming back, my birdies are going up as my proximity to the hole is going thru the roof, and it’s leading to confidence across my game.”
  • SASpeeder: “Not shooting under par quite as regularly anymore but still gaming the same equipment. Driver: Taylor M2 9.5” 2016 model with Diamana BF 60TX shaft. Irons: Miura CB1008 with KBS $Taper S+ shafts”
  • u2hockey14: “Adam Scott went back to his Titleist 910D3 this year due to accuracy issues, and he started to play better instantly. The bottom line is, for accomplished players, if you find a driver you can hit straight and are confident with it, stick with it. The extra 4-8 yards you get with “today’s” technology isn’t worth giving up that confidence and accuracy.”
  • leejohnkieh: “I’ve recently gotten my scores back down to even/under par after I got rid of drivers that didn’t work. For me, it’s all about feel and look. I went from 910d2 to a 17′ M1 to an M2 then to an M3 and now to the Ts3 in a span of 3 years. Tried every shaft known to man and I just could not get by round after round with TM drivers. Wildly inconsistent. I’d play tourneys not knowing where my driver was gonna go that day.”
