I purchased an Apex 8 and the grip had a thin piece of friction-type tape on it so as to keep my hand from sliding up the grip upon draw. That came off in the first 2 rounds and I replaced it with horse-ankle wrap tape that I found from Tractor Supply. Yes it is used to wrap the ankles of horses hence the name. It is sticky not only when it is wrapped around the bow but to my hand as well: my hand does not slide. But after many shots it also gets slippery and my hand moves again. I have more tape but has anyone out there used a material or gotten a grip that keeps your hand in one spot over a long shooting season? I also have used a batting/golf glove that worked well but using that outdoors causes my hand to sweat even more and my hand starts slipping inside the glove.
