I have a Bionic Zone SS Extreme--one of their overseas releases, I got mine off ebay, but bowlingball.com has some I believe. The ball is great when the oil is lighter or has broken down. The only problem for me is I hardly ever need to use it, too much oil in y center and lots of carrydown. IN my 4 ball bag I break it out when nothing else in my bag is doing anything for me, and when I do take it out , I can string strikes with it. I ended up getting one for my brother for Christmas last year and he is a 200+ avg bowler , and he loves the ball when the lanes aren't so heavily oiled.
