Gypsy's can do lots of things. Besides pull carts, there's been some in jumping, western and dressage.
There's a stallion in our area we have had the pleasure to meet. Indigoinaction
He is a dressage horse. WONDERFUL temperament on him.
They are quite versatile IMO. But this is where my knowledge ends. I like them as a breed and hubby and I were interested in them for endurance/trail but decided there was too much hair to take care of. Also, they are still quite pricey from what we've run across. You can get crosses fairly reasonable but purebreds are still selling real high where we are at.
