Well, as long as you're in the area with a decent sized group, it makes sense to go for Duck Pond.
1) You really don't want to whack through that area again unless absolutely necessary.
2) Duck Pond has a tough summit to find - 2 bumps that are long and flat. There are reportedly signs on each bump and I would like to find them both, so a team effort with many eyes searching would really make it easier.
There are also remnants of a cut path to Anderson somewhere on Duck Pond mtn. The more people that are in the area, the better chance we have of stumbling upon it. I don't want to hijack this trip, since Kurt was the one to suggest it, but I always thought that it might be a better route if you spotted a car at Nancy Pond trailhead and started up Sawyer River Rd. I would take the Carrigain Notch trail to the remains of the fire road that it crosses, turn right there, and look for a way to gain the southern ridge of Lowell first.
There are trip reports on here from Oncoman and NH_Mtn_Hiker for the Nancy Pond approach. Oncoman reported 1/4 mile per hour type thickness in spots, although he was solo.
