That would depend on what the buyer is looking for. I prefer the B minis for breeding especially the mare, and I like some leg and good hips. If the buyer is looking for halter horses they will want a ASPC/AMHR horse as that is what is winning in the show ring, especialy at the National level. All horses are suitable for performance. so if someone is looking for a driving horse they will look for those qualities and if someone is looking for obstacle they will look for a horse that is willing and looks where they are going, etc. It is up to the buyer what type of horse they are looking for. Some of the smaller minis will do very well in halter at AMHA and not place at all in AMHR so again it is preference.
