Big Eq, but ask your trainer. They will know exactly what you need and your style of riding!
If you want a pretty good horse, I suggest you get in touch with people that have a lot of contacts in the horse world. Now, I don't now how it works in other countries but here in Sweden that's the best way to do it, if you want a really good horse. But you never know! You can find a good horse on the internet too.
Good luck! ♥
I love this website called "Big Eq" their awesome, have a wide selection of horses, and it's very easy to find what your looking for
