This one issue is disturbing me a lot. I read Dr. Dave's book (The illustrated principles of pool and billiards). In his book listed as principle 2.8 third point down in the box it states that "your dominant eye, entire arm (especially below the elbow),and the cue stick should all be on the same vertical plane during the entire stroke and follow-through. On his website he doesn't mention eye dominance in his best practices section at all and in this section he doesn't make it seem very important at all http://billiards.colostate.edu/threads/eyes.html .How do I get a definitive answer to whether eye dominance is important or not ? I'm cross eyed dominant so this issue is really bothering me. If eye dominance does matter should I learn to shoot pool with my other hand or should I wear an eye patch for several months to try to change which eye is dominant? I need to know and no one seems to agree, and even more frustrating is I really trust Dr Dave's material so when there is a disagreement on principles usually I'll just go with whatever he said but in this case he seems to think eye dominance is important while also thinking its unimportant.
