i have been to his shop and messed around with the dominant eye thing, he has a blinder I wore over each eye to determine which eye I was dominant in. I'm a mess I'm not right or left dominate I'm a little of both. We couldnt come up with anything conclusive. He has his theory and used it on Franscisco and it worked, so I can't argue with that. His theory works on most people who come into his shop he said. There is no typo on the Black boar site. His cues play great they are my favorite playing cues currently being made.
