I can speak to the Rome Agent. I rode the 2009 Agent for the past three seasons and LOVED it. (It even got stolen from me for half a season and the police found the guy who stole it and I got my board back. It can has gud karmas no?)
Haha, but in all seriousness the Agent rips. I ride northeast as well and it holds up really well in all conditions. I ride pretty aggressively and the thing can hold an edge very well. I only found it to get a bit chattery on the really really bulletproof conditions but thats to be expected as its a mid-flex board (sits around a 6 or so, 10 being very stiff, 1 being buttery).
I ride about 50-60% park, and I could do everything in the park with it. Jibs, tables, pipe, you name it. It can handle powder decently - I never set my stance back but I bet if you did it would ride as well as anything on a powdery VT day. Then again, I bought it knowing that I wouldn't really be riding much powder as an east coast rider.
I like Rome a lot. A friend of mine rides the Postermania and loves it - maybe something else to look into as well.
Good luck, hope this helped.
