Right now I use a close-contact numnah pad under my saddle on my tb mare. But I think maybe I need something else, a little extra padding in there, especially above her withers (or shark fins, lol). She hasn't acted funny, like its been uncomfortable for her, but I just wanted to close up the space a little in there. I tried a keyhole but it was too thick and looked dumb. Is there some sort of flatter type of pad that would work? Or is she ok with just the one pad??
