Good luck with your 10 ball break, I wish I could offer you some advice, but my 10B break is horrible, just horrible. Some guys have it figured out to a degree but not like the 9B break, when ever the balls are in a triangle 3,6,10,15 its awalys very hard to make a ball on the break hitting the head ball.
when your playing 8 ball and you have 15 on the table hitting the 2nd ball works for making balls, but in 10B thats a foul cause its not the 1.
good luck
