I have been using a barn saddle (I'm the only one that has ever used it) for like a year now and I've figured that I should get one of my own. It is a Wintec and I did measure it but I'm not sure how to convert inches into a tree size. The tree is 10 inches exactly; from front point to point is 5 inches exactly; and the gullet is 2 to 2.5 inches. I've looked on Wintec's site and searched for a chart but I just can't find what I need! Thanks for your help!
