Thanks to everyone for their help on the Whirlwind. The posts were very helpful. I plan on purchasing the Whirlwind, and if for some reason the out of box condition (polished) isin't a big enough upgrade over the Tornado then I will take the advice to knock the polish off. Thanks guys, also appreciated coments on the other balls and the V2 Sweet. Although I didn't post any specs in my bowling profile, I feel still comfortable knowing the WhirlWind is believed to be a strong enough ball.
