It could be the 16" track? Just thinking out loud here.
Sledsrock:
X2. The track is part of it for sure, as a 16 is definitely harder to roll it on its side, however with XM's new 12" rods in the track, the edges should flex more, and that should make it handle more like a 15".
What I am wondering is more related to the front end: Now that the track and skid flex, will it be predictable on its side or just plain twitchy? I keep thinking this new design will turn and lay over very easily, but one mistake and it becomes a rolling pin!
If I was Burant, this wouldn't be a problem, but unfortunately most of us are not. Like most people, if I screw up, I let the sled go and it USUALLY stays upright without a rider.
If its narrowness and flex causes it to dive, we'll be doing alot more shoveling next winter!
