No, never ridden a TWH. Their gait is not natural and is coerced with implements of torture. I would never encourage cruelty by participating in such a breed.
Plus.. they look horribly NOT smooth to me.
If you meant.. have I ridden any other kinds of horses.. which I dunno what you meant, LOL.... but yes... all my formative lessons were on other breeds. I took english lessons to start on ponies then various breeds that stable had.. like mixed Tbs and such. My much more frequent lessons later on were Western and was purely QHs. That was the instructor lady I was complaining about some time ago who was always going on with popping the bit and kicking harder.
Thats one more thing I love about Pasos... cluck cluck.. away we go!
