One model that I have not seen mentioned is the Avant
Garde. Unfortunately, I haven't done a trial with this saddle yet, so I don't
have any great insight to share, but I plan to and am really leaning towards
this model.
It has the deepest seat of all the saddles ....
*It's a lovely saddle, unfortunately it has a
shorter flap than the the other dressage saddles, so didn't work for me at all
with my very long leg when I sat in one...
