Air Ride Saddle

I'm planning on investing in a new saddle pad, but I'm having a little trouble deciding which to get: Professionals Choice or Classic Equine. I have it narrowed down between which 2 I'd like: either the pro choice smx HD air ride (shiloh style) or the classic equine wool felt pad. The pro choice pad would be 34" x 36" whereas the classic equine pad would be 31" x 32".

I want a pad that will hold up and last for a long time under heavy use from anything from showing, barrels, roping, trails, and breaking/training young horses.

Ignoring the price difference between the two, what would you say the better pad would be and why? And what about size? Do you prefer the larger pad or the 31" x 32" only and why? Any experience using either pad? Any helpful info would be great! Thanks!
