I use a bateman tab, but when my fingers bother me, which is very rare I also put on a Damascus glove, it doesn't seam to effect my shooting at all. Naturally once the pain subsides, I switch back to just a tab.
I will also say I shot with a glove since 1957, and only switched to a tab just two years ago at the behest of a three time world champ and a two time national champ. He told me once I get used to it I would never go back to a glove and, while it took awhile to adjust, he was right, I would never go back to a glove ! He was also insistent on it being a Batemen Cordovan tab.
