The two railer is clearly the easier shot to execute because, as you said, it makes the object ball bigger. However, after years of repetition I came to recognize when it has a greater chance of scratching. Not saying this drawing is one of those situations, I was just throwing stuff out there that I have had success with. I would shoot the one railer sometimes (just enough to get SJD licking his chops ) if I felt there was a high probability of sliding off the object ball and scratching in the corner.lll said:senor , with the 10 ball off the rail would you not try to come off the long rail ( short rail to side rail)to end up in the same position. the 10 in that position is a bigger ball as i understand it . to hit it directly from the short rail if you are alittle off you hit the 10 towards his pocket and the q ball on the other side of where you want it. no?
