Does it have some thick support around the withers? I needed a cutback pad that will hold my 48lb saddle off my horse's withers. That's why I was so hesitant in getting it. I wasn't sure if it was thick enough/strong enough to keep it lifted.
It doesn't have anything special around the withers, tho they may sell one that does. The pad I have I would bet is not good enough for you! :)
