Should accuracy lines be drawn on pool tables?

[RacerX750]

There are chalk pencils made for marking cloth for tailors and dressmakers. Easier to control than snapping a line. Search on "Dritz". If you draw lightly, it will be gone in a week or two even without rubbing.

Dressmakers pattern marker. Once rolled on you can vacuum the excess to lighten the line. The line gets fainter but lasts for several washings with a damp microfiber towel.

If he can't make a rack straight without a line, he's not a player.

Watching league players rack more often than not the rack is not straight. I’m sure the best league players can give you a straight, tight rack, but not the other 90%.
