I just switched to a tab and I finally tried the saunders pak tab. I has a slick plastic instead of calf hair. It has different layers you can change out to give it different thickness. I settled on 3 layers the back is leather, middle is harder plastic, and the front is a slick more bendable plasctic/rubber type material. Oh and it has a spacer too.
Very slick, great support for fingers, and very comfortable. Never had a problem with it hurting my fingers like I have with calf hair tabs.
Even though it has 3 layers, you can still feel the string, and it does not feel too bulky.
just my 2 cents
