RE: form a grip
I' d stay away from it if I was you. I' ve seen several people try it over the years, they always wind up wishing they hadn' t.
One way I get the same grip every time is, I wear a jersey glove. Not the ones with the dot grips on them, just plain old brown jersey glove. My hand slides into the same position, every time, no matter how hot or sweaty my hand is.
