I probably would skip the snow pickets for north east climbing. Never found snow packs deep and consolidated enough for picket to be useful in my personal experience.
For general NEI/WI 2 in the north east, stuff like Huntington Ravine, North Face of Gothic, Trap Dyke, I wouldn't even bother with pro. But if I have to carry something, then 3 to 4 10CM and 13CM screws should do the job.

I disagree (slightly) with divnamite about snow pickets. In the easier gullies of Huntington such as, say, Central, the climb is mostly snow which can be deep and hard enough to use a picket. If you want "a little protection," then a picket is really the only choice (no place to put a screw). Even on the tougher climbs in the Ravine, a picket can be useful here or there. Depends a lot on conditions.

But I agree that most of the places you would use a picket can be reasonably soloed, so they aren't critical.

5 screws and 2 pitons. I would also skip the pickets.

Bingo.

I agree on the screws - 2-4 of them, 10-13cm.

Bring 2 single-length runners, and 2 double-length. You can often sling rock shrubs on that terrain, so they are nicer than draws. On NF of Gothics I'd bring 1-2 screws and 5-6 slings for simuling, since there are so many trees to tie off. This used to apply to the Trap Dike, not so much anymore.

In the Huntington gullies, rock gear abounds. 3-4 medium-size nuts and/or tri-cams are usually quite useful. For simuling Odell's I used a couple short screws, maybe 4 nuts, and 3-4 slings. That was enough for the whole thing (above the steep ice start, which we belayed).
