I have always shot split finger with a glove, but recently purchased a Black Widow split finger tab. It does not feel natural to me, and I am consistently shooting high and left. I think it is the right size, but I can't be sure. Any words of wisdom would be appreciated.
If you are trying to switch from a glove to a tab, I would recommend a tab with a spacer first. I have tried that BW tab your speaking of, and I didn't like it either.
I now shoot with the Fred Eichler Cordovan Leather Shooting Tab from 3 Rivers.
