I have my IQ 30 with a 4 x 5 x 1 for a skid snap response. Very pleased with it, but it was very touchy on houses with strong backends. I ordered the Phaze, just to try it out. I put a 5 x 4 x 3 for length and backend. I wanted it to be more controllable. I am trying to throw the ball straighter so I can bowl better on sport conditions. I have been extremely pleased with the control I have. I was concerned that when I moved in I would lose carry. I still have good carry with the ball even when I have to move in. I really haven't had a good bench mark ball, but I think the Phase will be it. Now I have ordered the Fight and will drill it to start rolling earlier, to see if I can conquer the Nationals pattern.
