I think the fact is that the game has changed, in terms of lane surface and oiling procedures, and to create the same ball reaction that the original Blue had back in the day, a few changes probably had to be made. I've had a urethane, (the Black Messenger actually), and the ball reaction was great....when the lanes were just right for it, usually pretty dry, not a very versatile ball for me at least. With the particle coverstock, and the lowered differential, I think this ball will provide a ball reaction that I don't have in my bag right now. I get what you're saying, and in theory, it is an excellent question, and it really scared me when I threw it at the Demo Days, and the ball did very little, but since the tweak in coverstock, I'm going to drill mine tomorrow, and I'll post the results as soon as I get some good info on it.
