06 vs 07

[scufty]

I had a 07 Adrenaline last year and for the most part reliability has steered me away from it so I bought a 06 800 SummitX whats the real differences in these 2 sleds and what are the thoughts on my change? The only thing done was the track has been changed to the Challenger( I believe that is what its called) (the better track)
Opinions pls and thanks

tough to beat the 06--i still have mine as a spare this year---i had a 07 and after i put the powdermax track on it was a great sled
