Totally understandable - you need to sit in them while on the horse to get a good feel for what it is you want and don't want. I'm on the saddle search myself - I have to get rid of my Wintec 500 A/P because it causes pockets and bridges - sooooo, I'm on the frustating journey of finding another saddle.
Are you looking for an A/P saddle? I have one for sale that is in great shape. It's a Collegiate Senior Event saddle.. It's so comfy, I honestly don't know why I'm selling it. I sent it with my mare 2 years ago when I leased her out and now that the people are buying her they only want to do dressage so they're buying my dressage saddle and giving my back the A/P to sell. It's a Med 16.5". It's kind of small.. I think I might have a little trouble selling it.
