Thanks guys. I've been checking Ebay
. Before I realized just how big a saddle I needed, I did see a couple of 24" saddles, but I missed out on them. My 18" saddle is pretty snug, and a 20" would be less so, but I was afraid it would still not distribute my not inconsiderable weight well enough on the horse's back.
Most of all... Thanks for not being judgemental!
