That is ok...a knight will always require a shield so should you ever get the time, I'll be waiting! You've adapted Gaffer's suggestions beautifully!
Anyhow, yes, it is near impossible to find a shield strapped for a southpaw unless I commission one...not a huge deal but every once in a while I'll see one I really want (like the Crusader Shield from Windlass) but of course, its only for orthodox folk. Its ok...I'm the only one in my right mind, far as I can tell! lol
