I have some 2013 Line Blends I'd be willing to part with, they're in probably 7/10 shape or so. Been skied every year since then but only for a few days each year. Not sure about giving them up, so I guess this is just a feeler.
My brother has 2013 Chronics in similar condition, but I have yet to ask him about selling them. They may have been mounted twice as well.
