I have a Thoroughbred gelding, 15.2hh. I don't know if conformationally or not, he would be considered as having high withers, because I don't really understand what this means, so I will let you see for yourself .... (yes there is another horse standing behind him in this picture, sorry) Currently, the only saddle I own is whats labelled as a "medium" gullet Kincade All Purpose, and of course, its come to my attention I hate All Purpose saddles. I don't feel safe or secure in them as I've always used a Stock Saddle. And as for the saddle itself being "medium" gullet? It looks wide, and it sits on him like a wide as well, so I'm not sure. My best friends actual medium gullet Status All Purpose fits him pretty near to perfectly, but again, I just don't feel secure in an All Purpose. So I've been looking for a Stock Saddle type, something a bit more "holding" of the me... And I've been told because of the types of backs Thoroughbreds have, that rather than going with a Stock, I'd be better off with a Half Breed, but I'm not sure how the half breed would be a better choice, as aren't they styled more like the western saddles, with the flatter base? How would that help on a high withered horse like a thoroughbred? Others have said go with a stock over a half breed because the half breed has the flatter base and it won't sit right on a thoroughbred, which I would have thought the case, but a friend of mine uses a half breed on her Thoroughbred and has no problems, so I'm lost as far as what I should use on my own horse, I'm a little confused. I keep getting conflicting information on what would be best or not. I just want something rugged, hardy and holding, like a stocky/western type, with the pads for your knees and all that stuff. AP's/Jumping/Dressage saddles don't make me feel secure at all.
