English or Western: Which is most difficult?
What's your opinions on it?
Personally I believe English because you have to follow so many rules about equatation and such.

To me it's english hands down
I rode western with my friend in some shows before, not easy-but not as rough as english

To be a correct rider they are the same. You use your body position/weight to both support and change/ask your horse to perform certain movements.
To just have enough balance/strength to stay on top of one and turn right/left/stop. Then Western is easier there is more saddle to help keep you there. But to be able to RIDE. A western reining horse or a showjumper tackless-thats riding.
Learning should be fun, try to find an instructor who will teach you without "teaching" Try this while mounted turn as hard as you can in the saddle, your horse will turn. So your instructor should be able to help you with circles by doing things like that instead of screaming at you- Thumbs up, heels down,sit up, look up,don't lean,bend your elbows...It IS hard to learn that way.

Okay, all things considered, the basics are the same. But posting would make English oh so much harder and that's something you just don't do Western. So, for me Western is easier.

Oh, but cowboys do post and their good at it. Really the only Western discipline I can think of that doesn't post is WP. They call it long trot. I'm not sure how far you may have to drive but find a working ranch or even a show. Watch @ the ranch those horses Trot and the riders post and in the events except pleasure[reining,working cow,cutting,roping,stock seat...] They trot in warm-up and again the riders post. Even been on trails where everyone was trotting and the westerns couldn't jog to stay with us, they trotted and posted or loped up. I ride both and maybe just ride to much as I find both to be about equal and do show western so I understand the sit there thing.

Okay, yes, western folks do post during warm ups etc. But that's just to get the horse warmed up and the thighs and knees going (or give the butt a break!). I have never had to post in a show nor have I had to worry about posting on the correct diagonal while showing western. Sure we had to do an extended trot, but we had to sit it. Unless there have been massive changes in how Western shows are judged in the last 20 or 30 years (OMG... it's been THAT LONG?)

Ok You Win!
