RE: Tornado BB
well, I only have the Syclone Pro with the Infinity, and I can say I'm not impressed...I spent the whatever I did (#28, or $38) for the vortex 2 needle carb, I bougth the single speed transmission from the XP...about the only upgrade I really like is the on piece aluminum upper brace, and the aluminum shocks...Although I think the plastic would be alright if we could make them a little more adjustable...so basically, I've turned my Pro into an XP....go figure...LOL...
