I use several different collegiate eventing saddles (a 17", 17 1/2", and 18") and... I ABSOLUTELY LOVE THEM!!!!!
Allot of my friends have them, or the jumping ones, and everyone loves them.
They're comfy, keep you in the correct position, and they're really sturdy.
The ones I use are several years old I think, and they're in amazing condition. Everything about them is great. I like them as much as my instructor's stubben.
I was actually thinking of buying the collegiate dressage saddle.
so I love them, hope it helps!
