I bowl alot on sport/PBA patterns and was thinking about getting an Invasion, but I'm not sure if I really need one. I have two Mutant Cell's and love them both on the long/heavy patterns. Mutant #1 is a 5 x 3 pin down drilling with factory finish to be smooth and predictable on the fresh backends. Mutant #2 is drilled 4 1/2 x 5 pin up at 4000 to give more length and angle in the carrydown. There has been a few times when I could have used something a little stronger because the backends on the long/heavy patters can become pretty soupy, but usally made due with what I had. With this setup would an Invasion be worth the money?
