I've been using the EW Bateman three under and it's a great tab. The leather is a bit thin. Not worried about it wearing out though. If you really like to feel the string this may be your tab.
However, I just got a couple of Skookum Cordovan tabs from Alaska Bowhunting Supply. The leather is a bit heavier, the tab has a removable finger separator and the cord lock on the elastic finger strap is a nice convenience. Lifetime guarantee.
I don't think you could go wrong with either one.
