Thank you so much. I tried your suggestions today. I abandoned my rail bridge & replaced it with my loop bridge, but lenghtened it considerably. I put the CB on the head string line, slightly off center to the right. My first hit on the head ball deflected slightly to the right. As per your suggestion, I moved my aim point to the left & the CB stopped in the center of the table & right in line with the spot where the head ball had been. I made a ball on 7 out of 10 breaks, mostly head or wing balls & stopped in the center of the table with good ball scatter. Just like the textbooks say it should be. I am using my new 21 ounce Sledgehammer with no miscues. On 2 occasions, the balls moved fast enough that I did not see them go into the pocket.
Thank you. Thank you. Thank you!!!!
