Hey man,
I have a pair of the 2017 Mantras, the second year they were reverse camber. They’re 184. I had them sitting in plastic until last week. I’ve skied 1 resort day on em. Not my style. They’re mounted for a bsl I think 306 or 309 (27.5 full tilts), with new STH2 wtr13s. One ski has 2 sets of holes for the heel piece, as the wrong jig was used initially. But, they were sealed. I was thinking $300 for skis only, $400 w bindings. Can send you pics if you’re interested.

Thanks,
Ryan
