What to breed with

Question
I have a 19 month old mustang filly that I plan on breeding at 4 yrs old. Her mother was 14hh and could jump 5ft and she is supposed to get between 15-16hh. I want to breed her for a jumping foal but am not sure whatto breed her to. I am deciding between a arabian, mustang, or theroughbred. Do you have any suggestions.

Answer
if you want a tall horse then breed her to a throughbred. But if your wanting the horse to be a purebred then breed her to another mustang.....if I were you and I wanted a jumping horse then I would breed her to the throughbred since jumping runs through their bloodlines.
