I have a horse with a VERY short back/space for the saddle. He also has large shoulders, a bit set back, and a forward girth groove. Yes, I really won the lottery here. :winkgrin:
I haven’t been impressed with Albions on him. Still too long. Even a shortened SLK. I picked up a Karl Niedersuss Symphonie that has come heavily recommended that I will try today. I think it will be too long as well, but I bought it cheap enough that I’m comfortable reselling it.
Kent and Masters were recommended to me, Kieffer also makes the Lusitano, Inzell (even shorter), and Amsterdam models that are good for a short back. Kieffer saddle trees are adjustable and they are wool flocked. They are next on my list as well as Harry Dabbs/Jaguar. They run short too. The Sommer Esprit is within your price range and is tailored for a short back and shoulder freedom. I think their trees can be adjusted by a saddle fitter but I cannot recall.
I also opted for a Total Saddle Fit girth due to the large shoulder/forward girth groove.
