Picked these up after getting a set of chronics last season, so far Line's quality is consistently amazing. Definitely beat on these things running over rocks early season that should've torn 'em up (same with my chronics for that matter) and it didn't matter at all, barely a scratch. They inspire a lot of confidence, dampening out chatter when snow quality is less than ideal and pretty much just crushing through anything that gets in the way. I've mounted Dukes on 'em so my setup is a little heavy, but it's really only noticeable while trying to hop around in tighter spots. They're manageable in moguls, but it's a lot more work. Haven't tried the AT thing yet, but I'll update this or something when I do later this season.
