Glen, when I first saw the core of the Onslaught I thought awesome...and I thought it looked alot like the Track Phenom core. Well, I just drilled a Phenom for a friend of mine, and he had Mo Pinel drill an Onslaught for him. There is no comparison. The Onslaught seemed like a dud. I guess I expected too much out it. It does not seem to be half of the ball that they Hercules is. Atleast for him it isn't.
