I am new here and found this little board and have been reading it alot lately. I have just recently been comparing different saddles and trees and ones that will fit most horses. I ride usually high withered appendix quarter horses and they just dont seem to make production saddles to fit them very good. I currently have one custom saddle that fits just about any horse I have ever ridden and it has a 6" wide gullet and not sure what bars it it has but it fits nicely. I have another saddle on order and I did ask the maker what would be the best for high withered horses and at the same time something that would fit everything. His reply was a 6" gullet and northwest bars in the tree. There doesnt seem to be much info available to the general public about bar angles except the QH, Semi QH, ect. I do have to wonder what a saddle with a 7" wide gullet fits. I have a production trophy saddle I won with full QH bars and a 7" gullet and it doesnt seem to fit anything real well at all. What is the difference between say, AZ bars, Ellensburg, Wade, and Northwest bars? All information would be of help. Thanks
