I always thought cross dominant was an advantage in the your head will be slightly tilted to the inside, putting your left dominant eye naturally over the cue while your right hand strokes. Left foot naturally falls out and forward giving you the angle, and the cue is naturally on a line across the body, not held out and away like right eye/right hand shooter can do. The last time I checked Ronny Osullivan is the same cross dominant, right hand, left eye, slight left off center chin.
"Snookery" great word and completely relevant to the discussion.
Nice one.
Yes, to the beginner...it doesn't hurt to get snookery from the start.
I only mentioned it as a flaw because it has been speculated that Morra’s extreme left eye dominance led to his shoulder/neck injury and has forced him to shoot left handed
