WHY HE PLAYS JUMBOMAX
“I play Tour Series (Standard Jumbo) because it gives me incredible feel and stability. It helps me deliver a quieter clubface with consistent grip pressure—all things that improve dispersion. After having surgery on my left wrist, this grip still allows me to train as hard as I want, pain-free. I also love my JMX Pistol Pro putter grip.”
Gira de Golf Profesional Mexicana
Derek Trofimczuk
Derek Trofimczuk is a professional golfer who currently competes on the Gira de Golf Profesional Mexicana. He has one professional win.
WHY HE PLAYS JUMBOMAX
"From a feel standpoint, the size of the grip makes the golf club much more comfortable to hold. As far as performance goes, JumboMax grips help me keep the face slightly more open at impact with a shallower angle of attack. This results in the ball starting a touch more right with less curvature, higher launch with a slight increase in spin. As a natural drawer of the golf ball, I see this shift in performance characteristics to be very beneficial."
PGTI Tour, China Golf Tour
Joshua Seale
Joshua Seale is Uganda’s top-ranked professional golfer and has more than a decade of experience on tour. Since turning pro in 2014, he’s held a tour card every season, competing across international circuits including the PGTI Tour and the China Golf Tour. A proud representative of Ugandan golf, Joshua is aiming to qualify for the next Olympic Games — building on a career milestone that includes his historic win at the 2016 Uganda Open.
WHY HE PLAYS JUMBOMAX
“I made the switch to JumboMax for the feel — and I stayed for the performance. The grips help me square the clubface more consistently and have added a few miles per hour to my swing. That combination of control and speed is tough to beat. I play the Tour Series Large on everything from driver through lob wedge, and I use the Split Grip SG1.0 on my putter.”
