I know people believe in the death of coverstocks. Most of them point to C300 for the death.
Let me start by saying this----I had a C300 Complete Chaos, Total Chaos, Black Chaos, Rock On, Rock, Reaction Roll and a few more. None of those balls died on me and they each got up to about 250 games before I moved on just to try new equipment.
My dad has a Black Chaos with ATLEAST 700 games, maybe more. He keeps the cover clean, when the cover gets a little shiney from use and oil he simply revives it and puts the 800 grit finish back on it, a light scuff and away it goes just like new.
He also still has my old Complete and Total Chaos, GOING strong, both of them.
I have no worries in buying a Phenom, except that it will hook too much and not get used as much as it should. I will have it laid out with a slightly more tame drilling than my Super Freak.
