I think Storm is figuring out that the Virtual Gravity was a great ball, and every attempt to improve on it in the high end asymetric line has not resulted in a great core shell matchup. There is a reason all the staffers are throwing primarily Road balls and the frantic. Now the IQ. there is such a thing as overkill with friction and core strength, and the ball makers have all hit the wall. Look at Brunswick. The Versa Max and now Maxxed out hit great and may be more vesatile than the Nexus balls.
Instead of asking what will hook the most, ask what the pros ask. What ball will hit the hardest on a broad range of conditions. On a house shot you can hook it all you need with a urethane ball, and probably carry just as good.
