While Corriente makes a great affordable saddle (and I loved the one I had until I got a new horse that it didn't fit), you have to have a horse with the right build for it. There is only one size tree - a 7"+ gullet and full quarter horse bars. It is a well made, very heavy saddle but if your horse doesn't fit that size, it isn't going to work.

I'm in the process of fitting the new mare to one of his saddles.
If you have a horse with very different body types, you really need two saddles. The flex trees are good up to a point but if you have a horse that takes a semi QH bar and another that is a full QH bar, no saddle will truly fit both.
