I've found that the knee pads that are built into the cantle area of Australian stock saddles REALLY help my riding and balance. I want to take my saddle in to see if some could be designed and attached over the western saddle I ride in. Is this something that has been done before? Is it possible to do on my saddle, or on a saddle in general? I am reluctant to buy an Australian saddle or a half-breed one because the fit on this one is already so good for me and Milo.
