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."

WHY HE PLAYS JUMBOMAX
"The moment I switched to JumboMax, I instantly had a totally different awareness of my club face. The tackiness of the grip and the perfect size for me (XS) feels like I can apply more force to the handle and gain more control at the same time. This and the additional confidence it gave me, led to winning my first event after I put JumboMax in my bag. And this event was the World Long Drive Championship 2022."

“With the amount of range sessions, practice rounds, and tournament rounds that I play, I was going through grips on a monthly basis. Since switching to Jumbomax, I can go a full year on two sets of grips… that is amazing! The best part is, the more you use them, the better they feel.”
