4 index here, I have had these grips for 3 range sessions so far... My stock shot shape is a fade/cut, and I can work the ball either way on command... Despite what many have said about larger grips, they DO NOT make everyone start slicing the ball or magnify a fade/slice, in fact, quite the opposite is true for me... The larger grips reduce a lot of tension in your hands allowing for a better release of the clubface, and making it easier to keep the face square... For me, my stock cut is now straight or a slight draw due to a smoother release and being able to keep the clubface square more easily... I can still work the ball either direction with minimal effort, flight it down, launch it high, everything just the same, and with less stress on my hands... A full range session (100-120 balls) usually cramps my left hand, but not with these grips... For reference, I wear a standard Large glove, and use the Medium JM grips. (or a Small built up to a Med with +6 wraps)... Love these grips, total game changer for me, they are on all clubs now, wish I had these 20 years ago!

Two range sessions in and I'm floored. I've been golfing for maybe a year and a half and had lost my way with my driver/woods. Figured I had nothing to lose, so I put these on and felt the issue with my swing immediately. By that I mean I had a more intuitive feel of my club angle. I corrected my swing path and by the end of the range session I was controlling shots 230-250 with my 3 wood and sending drives out of the range. Excited to try these out on the course.

I bought 1 of the jumbo Mac mediums to try on my driver. I fight a fade all the time. Not only did I straighten out the fade, I added a few yards too. I have bought five more to put on all my fairway woods, and am trying one on my irons also. I may have to go all Jumbomax

I love the jumbomax max large grips they let me play pain free

I am a high handicapper 6'3" large hands. Turning my hands over at impact my trail hand always ended up bloody and sore wrists. After a month of one on my PW I changed them all. Took a while to get used too but the hand and forearm pain is gone. Maybe XL aren't for everyone but their is a size for everyone.
