I've done Tar Hollow regularly.. pretty decent, youwont run into anyone on the south loops, blue or red. Have some really really nice ash groves down by the Firetower there as well, youc an park there and there's about 12 primitive sites about 400' into the woods. I'd follow the trail past those down and around vs. taking the two trailheads at the tower going the opposite way.
