Other guy,
No complaints on the core here, just other examples.
Actually, the solid crisis is one ball I have been strongly considering. The old book in our shop ( not my shop, just the one I buy at ) shows it not released yet ( old book ) with the same core as the pearl crisis had. I like this core better than that one and think it will work great. I am actually MORE interested than before, now that I know the core geometry for sure.
I also agree with your notion that a core needn't be obtusely asymmetrically shaped to have great rolling characteristics. I think people tend to take a good idea and try to improve on it to much, sometimes to the point of ruining it alltogether.
The K.I.S.S. principle. Thank goodness for people that agree.
