What kind of riding do you expect out of this sled, and where will you be riding.
Might make a big difference.
I would avoid the skinny track, it just get stuck quicker, there is a kid around here that started on a stock m5 at 8 (I think he was 8 and 9 now) this year he is hanging a leg and carvin it up, so if you think the 15" wide track is to wide think again, and the more power it has the easier it will get on it side and stay there. The easiest way to sidehill is with track spin. Whats a m6 weigh stock anyway.
