I taught myself
to do that years ago (like when I was 16-17-18). Plus shooting right or left one handed, and using my left foot as a bridge. Want a real game?
Try playing someone with your opposite hand one handed without no rails, good for training you to focus while shooting.... lol I really haven't practiced left handed for a long time, although I have no problem switching when I need to on a shot. I can still shoot 5-6 speed left handed. Only hestitation I wouild have is if it is a long shot that needs extra draw or english.
I don't know if this comes into play, but my Dad switched me when I was 3 from left to a righty mostly for baseball (family sport at the time) because left handed gloves were rare then, and thouight sports would be easier for me as a righty.
