TLDR; Rider who is neither picky nor technically knowledgeable about snowboard gear rides and loves his new Korua Dart.
Had my new-to-me Dart (156) out at Mammoth the past 2 days (17th / 18th). Tits deep in new snow, and this thing was a dreamboat.
Never having ridden a "powder board" before (have always been a one-board guy)... Mind-blown.
The riding this thing opens up in powder (vs a twinish all-mountain freestyle type board) is worth so much more than the price of admission. Steeps, chutes, faces / bowls, trees, low-angle... had non-stop fun on this thing. Allows much more intentional (purposeful? soulfully-aggressive?) riding and weight distribution without sinking the nose... Might be in my head, but I don't think so. So much more fun, so much less rear leg fatigue.
Was plenty fun on groomers as well. Detuned, I found it easy to ride, held a nice edge, easy to turn (bindings were set at +24/+15). Makes you want to flow. It's like a really capable board that took a bong hit; a competent but also mellow personality that you want to hang out with to charge, chill, or party.
Having said that, the board felt relatively heavy to me, though I think the extra mass might be (?) in part responsible for what I felt was a pretty nice ride. Having so much of it out front took me for surprise on the first hit of the day. I will have to learn to adjust to that. Same goes for riding bumps.
Have never ridden any other powder boards (I don't know if they're all like this), but I'll be keeping this one, and expect to ride it more than I expected.
Anyhow, that's my non-technical, uneducated 2 cents. Two highbacks up!
