Evil, I'm a shortybum, so it's a real exercise just to ground mount my 15.1 boy if I'm riding in my jumping saddle :P can do it easy on a 16.2 horse in a dressage saddle with dressage length stirrups though... guess the difference in length is greater than the difference in height, but since I jump, I'd like to be able to mount from the ground in a jumping saddle (with more practice and flexibility of course)
...but I like big horses better than small ones, so I'll take the good with the bad.
