Well, I tried dressage and enjoyed the discipline of it and the flowing movement. However, I personally am most comfortable with western. If I could I would ride like the native americans way back when, bare back and only your trust to hang on to.
Reining and reined cow horse are the to events that I breed for and show. Love the speed and control. There is nothing like having a horse running full out and then slide to a stop with the slightest of cue.
I ride dressage, but I learned to ride on a ranch... and then I moved to jumping, then when I got my own horse I moved to dressage. I think my favourite way of riding is bareback! Because I feel confortable bareback, and I can feel the horse and how she moves.
I currently ride both english and western. The disciplines I ride are dressage, bareback, western pleasure, and I've done a tiny bit of jumping. Does trail riding count, too?
My favorite is dressage since that's what I started with and I really enjoy it. It teaches you a lot and when it all comes together it's the most amazing feeling. I also enjoy barebacking and trail rides a lot.
