I've noticed reining horses tend to be on the shorter side. I'm 6' and I was wondering if I would look totall weird on a 14.3-15hh horse? As long as it's pretty compact and solidly built.
At least Reining horses are taller & have more substance than those little cutting horses & You see some big guys on those little cutters. I don't think you will look bad at all on a 15hh reining horse
I am 5'10 and this is me on my Dun It mare. She is about 15hh. If you look for HJ86/HDI lines they tend to be a bit bigger horses. Same with the Shining Spark line.
