Jason Dufner wore a Biggie Smalls hat, and used Mizuno JPX-900 Tour irons in Hawaii

Abiding by The 10 Hat Commandments, Jason Dufner wore a Notorious B.I.G. hat during the 2018 Sentry Tournament of Champions. Without his Titleist hat, since he no longer has a golf club or hat contract with the company, Dufner gave us a peak into his off-brand collection this week in Hawaii. And it didn’t disappoint. During the week, he wore a Bear’s Club hat, a camouflage Toronto Blue Jays hat, an American flag hat, and most importantly, a Biggie Smalls hat.
Also, as I predicted in our Two Guys Talkin’ Golf podcast, Dufner switched into Mizuno JPX-900 Tour irons for the week. It was an easy prediction for me, since the JPX-900 Tour irons are what many pros have switched into when they’re fresh out of club contracts. Just add Dufner to the list. And while Dufner was spotted testing a TaylorMade M4 driver early in the week, he played in the event itself with a Titleist 917D2 driver that he used throughout 2017.
Dufner, who earned a spot in the Sentry TOC with his win at The Memorial in 2017, finished at 10-under par and T11. Not a bad showing, although he did lose by 14 shots to the freakishly good performance of Dustin Johnson.
Until Dufner inevitably signs contracts, his hat and golf club choices will be a must follow in 2018. And we’ll be here to keep you up to date on anything noteworthy.

2021 Callaway Epic Speed Launch Day Report: Everything you need to know about the new equipment from Callaway

It’s the official launch day of the all-new Callaway Epic Speed line of metal woods, which includes both driver and fairway wood models—Epic Speed, Epic Max, and Epic LS. To summarize the newest releases, Callaway engineers are taking their artificial intelligence as far as they ever have by using it to optimize both the face and body of the driver to deliver forgiveness and distance increasing ball speed across the face like never before.
If are looking for in-depth information, on the ins and outs of the new designs and the technology that makes them possible, check out our full launch pieces below.
The new 2021 Callaway Epic Speed driver
The Epic Speed is the fastest swinging driver Callaway has ever made. The elevated Cyclone Aero Design gives players a clubhead that gets through the air and down into impact faster creating even more ball speed opportunities.
2021 Callaway Epic Max driver
The new 2021 Callaway Epic Max driver is a heater, but more than anything, it’s forgiving. Using all the tech bells and whistles from Epic Speed (AI-designed Jailbreak and Flash Face), Callaway made the Epic Max crown lighter with even more triaxial carbon, saving 19 grams of discretionary weight, which allows them to create an even deeper CG and higher MOI. A rear sliding 17-gram weight in the trunk to tune in launch and shape and the OptiFit hosel provides up to 20 yards of shot shape correction.
2021 Callaway Epic Max LS
Perspectives from the GolfWRX forums
- bcflyguy1 – I’ve also found the Max head to be excellent when lofted down and weight pushed to the toe; becomes surprisingly neutral when configured as such. Obviously can see where many will prefer the more muted sound/feel and compact footprint of the Speed head or may need the greater fade bias from the Max LS and its Trip Diamond-ish shaping. However, the Max offers a VERY rare combination of tons or horsepower but with sufficient traction control to keep even me from figuratively wrapping it around a light pole.
- noodle3873 – Just got back from hitting balls. My local Pro was breaking in his Epic LS 9° against his Mavrik SZ TD 9°. Both heads were built/hotmelted to the same weight. He was using GC Quad and brand new Srixon range balls (not ideal but numbers are like for like). On average he was getting more launch, more ball speed and a couple more yards out of the LS.
- mtp – I hit the whole lineup today. Not a fitting. Just trying them out. Was using the HZRDUS Smoke Green. LS was best for me. Prefer the shape, sound and feel over my current Sim Max.
- zeke66 – This thing is a beast. Hit it with a Paderson ballistic tp. I was swinging awful with all 3 drivers I was hitting including gamer, and wouldn’t leave the hitting bay until I started hitting it better. So I grabbed the Max Ls 9.0 and worked through it. Average ball speed was around 177 low 120’s with spin around 2100-2200, launch 12-15. When you catch one on the screws… it goes as good as anything I think.
More from the GolfWRX forums
GolfWRX’s resident equipment tester, Brian Knudson of the Club Junkie podcast, had this to say
Epic Max driver: A lot of draw bias, but easy to launch high and takes some right side out even with a neutral weight. Sound and feel are improved over Mavrik, much more muted and solid feeling. Center strikes are hot, and even misses carry some good ball speed.
Epic Speed driver: The best looking of the Epic drivers. Offers the most penetrating flight. Seems to be pretty low spin and easy to work the ball in either direction. Misses don’t stay online as well with more curvature. It is long and going to be a really good option for skilled players.
Epic Max LS driver: Very forgiving and offering a straighter flight than Max. Slightly lower trajectory as well. Toe misses hold their line better than the other two. Shots low on the face don’t get up as high as expected but still carry. Misses off-center still have good carry distance

Best utility iron of 2021 – GolfWRXers discuss

In our forums, our members have been discussing 2021 utility irons. WRXer ‘Krod10359’ kicks off the thread, saying:
“Just want to know your opinion on what new utility iron you have hit this year. Looks like a lot of solid offerings out right now from Ping, Srixon and Callaway. Let me hear what you have to say about these clubs.”
And our members have been sharing their thoughts in our forum.
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.
- hypergolf: “This…(photo above)”
- TigerInTheWoods: “Sim Udi is a beauty. Launches a bit higher and is a bit more forgiving than the P790 UDI which was really the benchmark for this kind of club.”
- craz-e: “Hard to go past the Srixon for performance and value. The current offerings from Titleist (u500 & u501) and Mizuno (HMB) are also great options and worth trying.”
- Golfingfanatic: “The new Callaway one is pretty good.”

Dufner did NOT play the M4 this week. He used his 917 driver. The fact that he would rather use what many describe as an inferior driver, rather than an M4, raises some questions

Titleist doesn’t go as straight or far but sounds and feels fantastic, so whatever tickles your testes.

More proof that TM are the best woods and Mizuno are the best irons out there at present. When money doesn’t corrupt the decision, the truth comes out. Got that, Sugar Daddy Rhino Bob?

Pretty sure TMag still does a wood contract for every tourney used. Or least they used to.
