Mr. Lamb has a good idea. I know when some buddies were getting ready for Special Forces school they began a regimen of rubbing aluminum powder (I think it was a cream but not sure), on their feet; the idea being the aluminum powder (same ingredient as in anti-perperants) would reduce the sweat glands from making sweat, which would help them with blisters. Now, that's not really what you were asking of course, but if it is bad its an idea. I know the deep grip on my grizzly is a pain to me when my hand sweats. It seems like I can't get a decent grip. I considered having a good leather craftsman or bowyer put a good leather grip on it but I never shoot it so I probably won't, but thats an idea as well if the situation arises.
