Here's my "high strung TB"
(we do hunters, with hunter derbys being our end goal, but we dabble in western as well.)
(ignore my english apparel and me in general, I was riding my other mare english while my friend rode this mare and I hopped on for a quick ride hahaha) hfwestern1.jpg hfwestern2.jpg hfwestern3.jpg
My point being, don't get hung up on needing one breed or another. Choose the horse that will work for you - the one you click with. Unless you are doing breed shows, if the horse preforms well for what you need, don't focus on breed so much but the individual horse.
Edit: I do just want to add that I would NOT recommend a TB straight off the track and/or a greenie (no matter the breed) for anyone less than an experienced rider & handler, maybe intermediate depending on the individual horse and how closely you would work with a trainer. My mare was green-as-grass when I bought her, halter broke and maybe a couple times having someone on her back before I purchased. She knew next to nothing on the ground and under saddle. That being said, I am an experienced rider and got lucky with this mare being extremely docile from the first time I saw her to present.
