I use the tab from 3Rivers identified as "Cordovan Leather Shooting Tab,Item Number: 5088X". I have a small to medium sized hand, and find that the medium size works best.
This tab has a cordovan face flap of just the right thickness, and a suede rear flap. Assuming you shoot split finger, the rubber finger separator is very comfortable. It has an infinitely adjustable stretchy loop which will accommodate any size finger as well as gloves. Finally, the price seems reasonable.
Best wishes,
Frank
