Hoping others with more knowledge of jumping saddle design and body mechanics can help me understand what symptoms emerge from different types of poor saddle fit for the rider. For example, what does it feel like when a twist is too narrow/wide, or the seat size is too large/small, or seat shape is too deep/flat, or stirrup bars are placed too far forward/back? And what do these different types of misfit do to a rider’s position?
My interest stems, of course, from trying to find a new saddle. I’ve come to accept that the fit of my current one is not right, but I’m not sure what exactly is making it so wrong for me. I’ve sat in a lot of different saddles —some of which I’ve hated instantly, and none of which have felt like an epiphany—and read a lot of different articles (e.g., Schleese, Trumbull mountain, saddle geek, COTH), but I feel like I’m still missing some key connections between potential sources of poor fit (like twist width or seat size) and the symptoms they commonly cause (like painfully bumping into the pommel or balancing too forward on the pubic bone or pinching with the knees).
So those of you who know something about fit issues, what have you learned?
(I know saddle fit is a complex issue, complicated further by the idiosyncrasies of a given rider and a given horse, and that diagnosing and fixing fit problems is best handled in person, on a horse, by a competent saddle fitter. I am trying to find answers to a simplified and broader question of what elements of a saddle design can be associated with which symptoms of poor rider position or rider discomfort, setting aside the specifics of the horse and saddle-to-horse fit. For the purpose of this question, just assume that the saddle fits the horse perfectly, that they go happily in it, and that the rider is not wildly mis-proportioned to the shape and size of the horse).
