Now that I'm on the UT bowling team, I am looking to improve and change my arsenal to better benefit me when we start traveling to tournaments. My profile states what I have now, and I am looking to add two balls to this list, and possibly a third if really necessary. I am definitely looking to purchase another Inferno as well as a Raging Inferno. My question is drilling related here. My current Inferno is a very weak, pin above bridge drilling, and combined with the number of games I've put on the ball, it makes small smooth arc into the pocket. With my new Inferno, I want a very aggressive drilling very a very angular backend. I would imagine a small axis hole needs to be added whatever the drilling may be. For the Raging Inferno, I want a drilling to compliment my Fuel on heavy oil. The other ball I was thinking of adding, but won't if not absolutely necessary is the Slayr for dryer conditions, although I think my original Inferno with its weak drilling will be sufficient. Please help me out here if all possible. I really appreciate all the help I've received through these forums, its been very beneficial to my game.
