I think she is way cute! Why not try HUS? It can't hurt! How competitive are the shows you are aiming for? Are you wanting to do APHA? A smaller horse with great movement will still be good for HUS IMO. Have you thought about all around for her? I think she is a lovely mover!
I want to be very competitive and yes APHA, I have thought about her being an all rounder so WP, but I dunno...I tend to do prefer to stick with one thing!!But im going to get her broken in english (hunter) then get her broken for WP so its always available.,
