Saddle advice- wide backed short-coupled horse doesn't like his treeless saddle
I'm fairly new to these message boards but read back through recent posts before deciding to post this. My apologies if it was just covered somewhere else!
I have a very wide-backed, LONG-withered, short-coupled Bashkir Curly gelding. He's seven years old and was recently diagnosed with Equine Metabolic Syndrome...meaning he's basically in the early stages of being an insulin resistant horse.
This diagnosis has helped me better understand his diet requirements and he has accordingly lost a lot of weight that he needed to lose.
When I bought him a saddle last year *nothing* fit him and so we eventually got him a Barefoot Cheyenne treeless saddle. It was the only saddle he would stand still for and seemed comfortable in.
However, now that he's lost weight, I have borrowed an extra-wide Thornhill endurance saddle that fits him well. I am not terribly in shape as a rider and I have to admit to feeling more secure in a treed saddle with kneeblocks right now. Also, Sage has an old injury to his sacroiliac joint and seems more comfortable with me getting on when I use the treed saddle now.
So I'm doing research into new saddle options for us. Sage is still VERY wide since he needs a Thornhill extra-wide tree, but he is clearly not as freakishly wide as he once was.
I would like a saddle that is secure out on the trails, and still reasonably light. Sage and I do some fairly intense up and down hill terrain on occasion and I can't see really being comfortable in the Thornhill endurance model we've borrowed.
So I'm wondering what suggestions people have for other saddles to try? Because Sage is so short-coupled I would hesitate to try an abetta endurance saddle again...any thoughts?
Thanks in advance for any input or advice, I know we have quite a lot of factors to consider here.
