They let me borrow it to try it on but I am not sure if it fits. I could fit an English saddle fine but I am a bit out of my depths with this one. I read the saddle fitting thread on here, and watched the videos, and my primary concerns are how the saddle is cut forward on the shoulder, and how far back it goes. I drew the chalk lines where her ribcage is and the saddle goes over it, but the seat but doesn't. And most halfbreeds seem to be cut forward at the shoulder, but I don't know if that, and the part behind the ribcage, really bears any weight.
For those who don't know, a halfbreed has the flat panels and fenders of a Western saddle, combined with the knee rolls and seat of the Australian stock saddle. They're quite popular down here.
Here are some pictures, I'd love some advice about fit. Besides the issues mentioned, it seems very stable, doesn't rock, and clears the withers, and I can also see down the back channel. Maybe some western saddle people can help, because it's more like a western fit I think, rather than English.
