The Fix is the latest from Radical Bowling Technologies in the Top Shelf line! Whats more, this is the most innovative core in the industry since the early 90's. The Fix provides a core that allows drilling both as Symmetrical and Asymetrical!
I am a lefty, ~16mph, 400 rev. I have drilled my Fix as symmetrical (pin down) drilling with dual angle #'s of 60*x 4 1/2" x 80*. This ball provides a strong solid coverstock which allows the symmetrical drilling to blend the lane front to back, without burning up. I have used this ball both polished and matte/dull, as needed based upon lane condition.
Being on the left side, we don't see a lot of traffic most of the time. That said, when we do see an increased amount of traffic and the ball track begins to force the ball to burn up too early and not roll through the pins correctly, or it simply overreacts, The Fix has allowed me to move my feet right and "ball up" and The Fix will still turn the corner downlane, when many other balls will not have enough "oomph" to turn the corner and go through the pins correctly.
I suggest finding the right need within your arsenal (Symmetrical or Asymmetrical) and get yourself a Fix! Then, once you have grown to LOVE that Fix, you go back and get yourself another Fix!!!
