I too recently have been taking a break from the glove and using a tab.
Ive been wearing out a groove on my Berlin ring finger glove so deep that it really hooks the string, and that has been toying with my accuracy...and a bit of pain.
I switched over to a Batemen cordovan tab.
After a few arrows all I could say was NICE.......really smooth releases too after trimming it down.
The anchor point was the flesh of my middle finger to the edge of my lip which I could never replicate with a glove because there is no consistant 'feel' if that makes any sense.
I might have been squeezing my nocks, and would never have been sure.
What my shooting needed was a bit more consistency in certain areas, and thats what I found works for me, plus my ring finger feels great.
Anyway, Im a newb, still searching, and so figured this observation may be worth a shot (no pun) investigating along with other ideas.
