I'm constantly trying out new grip methods, because I tend not to drop sticks, but to overgrip sticks. This leads to hand fatigue and I end up clutching the stick like a knife, rather than holding it properly.
I tried the dip sticks, but the pair I tried (Zildjian 5Bs) gave me horrible blisters when the dip separated from the stick and started rubbing back and forth.
I love the Pro-Mark Pro Grips, but they are expensive and hard to find. I didn't have any break-in period like the other poster did, and I never experienced any problems with overgrip or dropping the stick.
I'm trying Ahead grip tape now, and it's decent, but I don't particularly like the bumpy feel on the butts of my sticks.
I just ordered a can of Groove Juice's new spray-on drum gripper. They claim it makes the stick slightly tacky but does not stick to your hands. I'll be a/b comparing that against a new pair of Pro Grip sticks. I'm hoping it does pretty much the same thing, so that I can walk into my local shop and buy 5Bs, instead of sending away to Cascio Interstate every time I need sticks. I'll keep you guys posted.
