It's all about pliability, how well the leather will stretch over your pad. You'll see what I mean when you try to work the wrinkles out! This should concern you much more than the outside characteristics, all leathers will be somewhat slick on the shoulder once the pad is finished out. Thin pigskin works the best for me.

Best, Dan
