Twhgirl2, if you want any suggestions please post the pics. It's really hard to imagine anything without seeing a horse. BTW, my horse has a deep on her left just next to the shoulder. Muscling didn't help all that much - that's her conformation, so I just use extra-padding there (per the saddle fitter suggestion).
