Hmmm... could you specify how spring/summer conditions in PNW are like?
Here it means southern aspects being icy in the mornings, slushy at noon, windblown crusts everywhere... If so then I'd go with mid long board (no deep pow to float) rather on the stiffer side (to cope with the changing conditions) with good edgehold (e.g. RCR with mellow magne or alike for the icy patches).
If you look for a split, I was told that RCR or RFR suite better for surface contact/tracktion on crusts, but that's second hand knowledge. I've a RCR and know that skinning on crusts can be PITA and it sounded logical that a rocker won't help.
