I find the BW tab with ears provides more protection than the Bateman with a spacer that I also use. Why do you have to adjust the velcro after every shot? My tab is just about worn out but the velcro still holds fast. Has your velcro lost its adhesiveness? If so, night just tape the two pieces together. If shooting is what's causing the raw index finger, you're putting too much downward pressure on the string, which can be partially ameliorated by lowing your drawing arm elbow.
On the other hand, if you have a long draw and/or a short bow, finger pinch is the result, and no tab or glove completely protects against the effects.
