I use to help train and show for a gentleman that showed WP back in my 20's. I loved the slow trot and lope. (I think the really slow walk kinda sucks) But I have a lot of back issues and the slower gaits are so much more easier on my back. I can't even explain how good it feels to ride that smooth, barely moving trot, or that rocking chair lope that a WP horse has.
Once, I used one of the guy's horses to do a playdate. Mostly timed events. Of course I wasn't going to win a single one of them because I could walk faster than my horse could lope, but I was there just for the fun. One of the events was the flag race. You lope down to a barrel, pick up a flag and lope back. Well, my WP horse loped down (5 minutes later) we get to the barrel and I pick up the flag. She didn't like the flag at all and decided to buck. I swear it was the easiest bucking fit I had ever rode. I had the reins in one hand, the flag in the other and she was bucking so slow it was beyond easy to sit. The flag in my hand was going up and down...timed to her bucks. I almost felt llike a professional bronc rider. Sadly, when your in that situation, you never hear the crowd who was actually screaming at me to drop the flag. (never considered it.) So, I did the next best thing...and the only thing I thought of, I stepped out of the stirrup and onto the ground. That's how slow she was bucking. Who knew there was a WP buck.
I have my own horses now...so I'm aiming for those slower gaits that are easier on my back. I learned a lot from the guy I use to ride for. I learned things I liked and things I don't like. While I like the gaits, I didn't approve of his method of training. When training my girls, I still like the lower head set, that smooth sitting trot and rocking chair lope. Even when I'm out checking fence or moving cattle.
Anyways...I couldn't imagine riding dressage or a jumping/eventing horse, so I'm sure there are folks that can't imagine riding a western pleasure horse. Good thing there are many different disciplines you can choose when owning a horse. There is always something for everyone. Like the Paso Fino above...it looks strange to me, but there will be ppl that love it.
