Jump saddle that fits like Wintec Isabel?

Crux of the matter, huge shark fin withers short short back, the Wintec Isabel dressage (with NARROW insert) fits her but absolutely not one of the jump saddles in the barn does. Including a devacoux XC (sorry don’t know the model) a cheap talouse and honestly at least 6 more, they all just don’t have a deep enough channel. While I’ve found plenty that would work in the $1,800 range I’d like to be sub $1k. Is that even possible or just wishful thinking?

I totally get that dressage saddles and jump saddles fit differently but I figured the vast knowledge of COTH may be able to help. I’m from a time when everything went in a Prix De Nations whether it liked it or not. So I will definitely give you that my saddle knowledge is limited at best.

I’m assuming you’ve tried the Wintec jump saddles?

I don’t have access to any, but from my lay eyes they don’t look similar in build, I have an older wintec all purpose (no purpose) that does NOT fit her at all. same thing like a rocking horse on her.

Pre- or post-2010 Isabel? They fit horses very differently.

post 2010, it’s brand new.

I have a youngster that fits in the new Wintecs (he’s got a pretty flat back, and the older Wintecs were much curvier…I know because I have a TB that fits in those!) and the all purposes do fit very similarly to the Isabells. Can’t speak to any of the true jump saddles, however. I currently ride my youngster in a Black Country Tex Eventer. A Quantum might also work. Sadly you’ll be lucky to find either of those under $2k…

sorry just realized that it has the narrow in it NOT the m/w.
