People can debate that English, Western, Side saddle, Aussie, ect is the best way to ride but I say bareback is the way to go.
When I first learned to ride English I had a lot of trouble learning to sit the trot and canter despite having lunge line lessons and practicing stirrupless. My instructor had me ride the round, fat pony bareback which finally helped me develop a proper seat.
It feels like you're not going to be as secure bareback but I've managed to ride out spooks, bolts, bucks (the one instance where you can appreciate high withers

), and rears more securely than I thought I could. I really enjoy riding bareback especially when I've been having so many saddle problems with my horse.
