Your in about the same part of the country as I am and we probably hunt just about the same terrain.
I do most of my rifle hunting in Vermont and New Hampshire I do hunt bear in MASS. Though I own and love my marlin SBL witch is a superb brush gun. My 35 rem is really all I need for the north east. I wouldn't even feel under gunned if I ever get lucky and win the lottery for a moose tag.
The difference might not be much between the 35 and the 30-30 to a lot of guy's. But IMO the 35 gets the edge for bigger critters in the north east. Especially when you can load it up with some 220gr FP's.
One more thing I love the way a short brush gun handles but I can't tell the difference between 18 inches or 20.

That's my idea of the perfect north eastern brush gun and those are some 220gr FP's that I loaded up that shoot to the same point of impact as the hornady leverevolution 200gr at 100 yards. And that's the target.
