The evo is a park board but isn't that soft. It does chatter though.
The flex of the Proto is stiffer, but the same dampness.
Proto/SL sounds right up your alley if you're sticking with Never Summer.
Looking to butter and possibly jib later? Doesn't sound like the Trice would be the right board. Maybe the Riders Choice.
Arbor Coda but I'm not sure how well the full rocker arbors ride on the East coast. I've hit ice with mine before but I'm on edge until I can get out of there (and if it's the whole mountain I just go home). I've been on the Coda on something right next to ice and it was fine.
