I've been looking around western saddles for my high withered OTTB. I've found it hard to find something with a high enough gullet. He has rather narrow shoulders, and I am wondering if a gaited saddle might be a better fit for him? I have never had a gaited horse, so no reason to have a gaited saddle, but it is my understanding that the tree is narrower up front and gets wider in the back? Buckles is narrow up front, with a big ol butt (hes rather pear shaped); so do you think a gaited saddle would fit better than a regular old semi-qh tree?
Here's some pics to get a better idea of what his big awkward withers look like:
