There are some good tabs out there. I used a Martin Archery Mitt for about a year, available from 3 Rivers, which offers the max protection of any tab I've seen. Recently I switched to a tab made by Scott Teaschner that is sold through Rod Jenkins at Safarituff that offers a little less protection, but still totally adequate, that I like better. It is strictly a 3 under tab, but the Martin tab can be shot either way.
I'm sure most people shoot best with the minimum tab or glove that works for them, but for Heaven's sake, we're doing this for fun, not as some kind of Comanche rite of passage to manhood, and if something we're doing is causing pain, we ought to try to correct it.
