I have this saddle, I has a wintec, but it just didn't fit my boys back. The tree in the Thorowgood in rather flat, so depending on your horses shape, it may not fit, but then again it may fit brilliantly.
I've had it this whole year, got it in December, and no complaints at all! Super comfy, and supporting. The knee supports are annoying for me but help other people.
I've had mine for 2 years now. I use it 5 to 6 times a week. So far it's holding up fine. It fits my shark fin withered TB like a glove. It's a very sticky saddle. It's saved my butt many times over when my horse decided to be a goof out on the trails.
I don't have this saddle , but I do have an AP Thorowgood Griffin with the Fish system. I have owned for a year or so , it was used when I got it but it is super comfy and I love the seat.
I don't ride in it very often though as I mainly ride in my Circle Y western saddle that I just love to death, but as far as English saddles go I like my Griffin.
