Thank you all very much for the advice. I really appreciate it.
In response to a few of the questions, I’m currently horseless but lucky enough to be riding a couple of dressage horses at a barn in my area that needed a competent rider for some of the barn owner’s horses. They’re your typical big dressage warmbloods (bulky, wide, big shoulder, both around 17 hands). I’m an event rider but am actually shocked at how much I’m enjoying pure dressage.
That being said, I don’t want to spend a ton of money fitting a saddle to a horse that I don’t own, hence the search for a budget friendly used option. I’ll make the investment in something custom when I buy my next eventer in a year or two.
Do I actually need an 18.5"+ saddle? By the looks of it, yes. I’ve sat in a few 18" saddles, but the deeper seats with a high pommel tend to put me in a position that’s, well… uncomfortable for the male anatomy. What I really need is something with a less “helpful” structure (flatter seat, fewer blocks), forward flaps, and a longer stirrup bar which is exactly what most everyone is suggesting. I don’t need the added security, just something that gives me a little more room and doesn’t put me in a chair seat.
I’d love to find a used Stubben and have actually come across a few that may work. Again, thank you all for the help here, very much appreciated! Dressage saddles are fairly uncharted territory.
