Well I'm selling the good old M7 and am looking at three different sleds, The 08 Dragon 8 with 163, The 2007 M10 with 162 and then i'm also looking at some turbo apex's. I don't know alot about really either of them other then what I've red on here, mainly i'm just tired of running out of power. I want a sled that will have plenty of power, but that will handle as good as my M7 has. I'm betting they all will since their newer. I've always been a polaris rider some i'm more interested in the D8 But i don't know how people have liked them. Also I think the M10 would be a good power sled while not weighing what the apex would. I love to Climb and Boondock, I'm 6' 170 so what do you think.
