The Eminence is a great board. I ride mostly blues, some blacks, some trees and NO park...also on the east coast. Magnetraction and the C2 profile help with the east coast conditions. It's a pretty stable board, but the rocker between the bindings still makes it playful.
It's supposed to be a great board for the pipe, but mine will never see that unless I take a wrong turn.
I'm shorter and a little heavier than your wife and I ride a 149. I don't think you would want to go any bigger than that unless she is used to, and likes, a longer board.
It's very lightweight so it might not be quite as damp as the other two boards.
The Roxy Ollie Pop was also a super fun ride! Not sure which one I like better, the Ollie Pop or Eminence. The Ollie Pop is a little heavier, with a slightly wider waist so it feels a little more stable. It also feels a little softer than the Eminence, and with the extruded base it is not quite as fast. They are both true twins though.
The other two boards get great reviews too, so I'm guessing you won't go wrong with any of them.
