OK my friend, as I said, the Hybrid Dirty Bomb has had mixed reviews as far as their lifespan (see Lane1 forum here). I personally have thrown the Hybrid Dirty Bomb with 2 different layouts for approximately 50 games and I am not as sold on it's performance as some of the past releases to include the Uranium line. As far as the original Dirty Bomb, it is a pretty good ball from my experience also having thrown a few but will not handle Medium-Heavy oil as he stated he needed. Therefore, I stick to my original suggestion of the Solid Uranium "my friend." Good luck with whatever you decide.
