All of my horses have off side manes except for my stallion. His falls on the near side because of a callic (spelling??), near his crest. If I were to train it to the other side (which I tried to do), there is about a 4 inch section that would stick straight up in the air. I have had people tell me that his mane needs to be on the other side...too bad...it doesn't want to go to that side :). I have never been told anything about it in the show ring.
