I have never had the pleasure of owning a sled right out of the box...but am deeply considering it currently. problem is, I have some questions about the prey I am stalking. I am wanting 07/Summit/800-X/151, but being this late in the game what I am finding is that...i'm not finding any!. that being said, what I have been able to find is the Adrenaline package. Lookin' for feedback from anyone on comparisons of the two,purchase tips and pricing etc. I know, I know, I should have snow-checked one last spring, then I wouldn't have to be typing this. Any words of wisdom are appreciated. thanks in advance
