I have found that for me, it's best to go smaller on the tab size. I even have an old Wilson (Black Widow) cordovan tab they made many years ago in a small size that works very well for my large lunch grabbers.
On brand, you have to decide would be my recommendation, but I do like the Bateman cordovan since the cordovan leather is as good if not better than tabs I have costing many times more. Also like the way the Black Widow fits and feels. I bought three sizes (small, medium and large) at different times of Fivics cordovan tabs when they made them with a leather palm plate several years ago (they no longer make these tabs). I use the medium to shoot split finger, which is the style I shot for 55 years, and the small for three under shooting, which I started doing last year for 3-D type short target shooting. The large is too large for me.
