Been at this 40+ yrs and have never heard anyone say that burn-marks were a aiming/playing aid. Where do people get this stuff??I think it does affect play, but not in a physical way, it gives a visual aid. A kind of guide line. I use to play snooker at a friends house growing up. He was lucky enough to have a father who was a coach and had a table in the garage. Had some of my highest breaks on that table, and I always attributed it to using the lines which resulted from hours of him coaching students as an assist. Certainly played better on his Riley than I ever did on the Burrough & Watts at the club my dad plays at.
