RE: Sore fingers!
Hi hgsnpr,
I'm not sureI can suggest a heavier tab. Seems like the better tabs are actually pretty thin. The thicker the tab, the more chance that you risk getting unwanted grooves in it. If you are going that direction though, maybe try a cordovan type tab like Alaskan Bow Supply has. I think though that either way, a glove would probably offer more protection, again, I prefer cordovan tips.
With the bow that you are shooting, it would seem likely to get some pinch.
