I tried playing left handed - once.
Looked like a developmentally disabled blind gorilla with Parkinson's.
Never forgot a pistol match. The stage was six shots strong hand unsupported, reload, six shots weak hand supported. Both groups were fired at the head area of B-27 targets. I think the range was ten yards. I let a shot trickle out the side of the strong hand unsupported target! Annoyed, I hit a reload and came up with the weak hand supported. Sounded like full auto fire, dead center of the "head" and a tiny hole, tiny for a forty-five rapid fire anyway, I could squeeze two fingers through it. Another Master shooter was watching from behind me, "You are better when you shoot fast!"
I have found that most left handed pool shots can be covered by a standard bridge and moving my grip hand across in front of my body. The stick is in the left hand position but I am shooting with my right hand. Saw a pro use the same technique many years after I started just from the left hand being too stupid to handle shots.
I often wonder why we use the less coordinated hand for bridging and the more coordinated hand for just holding a loose grip. Doesn't seem right.
