Recently I've met this Thoroughbred, and I don't really like them as a breed at all but I really, really like this one. She's unbroken but I've been doing stuff on the ground and I am pretty sure I am going to get her, spend the money getting her broken. She's quite stocky, 15.3hh, sprint bred.
What I want to know is what I can do (western speaking) with a Thoroughbred? I would love to learn some reining but I am guessing I could never be competitive with a TB, but could I learn basic reining with them (with a professional trainer)? Maybe some team penning, but you seem to be able to use anything for that. What could I do, and would it be acceptable to use a TB?
