A thread about lights and pin point aiming came up and got me thinking, A friend mention'd lights help us to aim and find the contact points on the objectball and i use the cueball's 1/4 to aim on most shots using Hals aiming system. But sometimes the cueball is close to the rails and i can't see this part as i use the bottom of the cueball as a reference as pictured in my diagram and times the tables i play on the lighting ain't always good so what i am asking is should i adjust and train myself using the upper half of the cueball to aim for these times or what do you guys do when this situation comes up, the rail shots. The edge and 1/4 of the objectball i use for easy aiming references when i get down on the shot these parts i always look at depending on the shot if it ain't straight in, and i think Joe's system is somewhat similiar to this correct me if i am wrong. So should i always use the edge of the cueball to aim or the middle of the cueball rather then trying to learn something new as i know its hard to change something you already know and been using for along time. Thanks in Advance guys. Wub Cole 'TheConArtist'
