Every horse is different.
One of my horses needs the mustang roll, where the other needs a medium heel height and needs to be very round in front and more squared in back, because of him having ringbone and a stifle injury. It just helps with his breakover.
As long as you know that your horses are balanced, I think it’s all depending on the horse and more power to you for being able to do it yourself!
I’ve looked into some of the schools in my area just to try and save money. But some of the schools are kind of expensive and you have to live there..and I can’t be away from my horses that long.
