xwenhan,
As others have already said....and I'm sure you suspect....the Ice is the ball you want, with a tad bit of polish!
However, I have to disagree with those who say the KI pearl was junk! It's all about the operator! That is not a true pearl. It is pearlized, but I look at it as a strong medium oil ball. It gives great carry, and I have scored well with it in many tournaments, especially Carolier lanes in N.J.
The core in it is unique, and very continuous. This is NOT a ball that needs a lot of revs. Nuff said.
