My 1/2 Perch, 1/2 Morgan always placed in the top three at events, with dressage scores in the low 30s. He qualified for the AECs twice, but never made it due to flatweed poisoning (neurological disease). He could jump, and could jump well, but his canter was a LOT of work and he had trouble making time at Novice, due to his gallop being more up-and-down than ground covering. It was also very difficult to keep the weight off him - lots and lots of conditioning, even for Novice. Despite the weird mix of breeds, he actually took a regular wide tree saddle, normal/WB sized bridle (a mix), 52" girth, 80" blanket, and WB sized boots. Nothing special. He was also 16.2ish hands. He’s now the dressage pet of a young teenager and has qualified her for Nationals for dressage, with dressage scores in the mid 70s. He also looks like a tank now that he’s no longer being conditioned for eventing.

Personally, I would never own another draft cross unless it was only about 1/4 draft. THey’re just too hard to get and keep fit. Btw, Irish Draughts don’t really fit into this category - the ID are bred to jump, hunt, pull a plow, and take the family to church - not your typical draft cross. I am always amused when people bring them up in these draft cross discussions.
