I am starting showing really soon and all I have is a synthetic all purpose saddle. Would I be able to use it? I am doing hack class and rider and all that kind of stuff, but not a hunter or turnout class. Im only doing ag shows and then hoping to get up to higher levels. I know I eithee need a show or dressage saddle, idealy a show, but at the moment all I have is my AP. Would I be marked down at all???
