Just thought I'd give an update. I threw my old 28s back on for a while and finally got around to trying 32s again. This time I picked up 700x32 Panaracer T-Servs. Good news - They ride great even on descents...nice and stable. Very happy with the ride. The bad news (which isn't directly the tires fault) - I got 2 spoke side flats on the way into work this morning. Time for new rim tape. This happened on the front tire last time I switched tires, but I was lazy and only replaced the rim tape up front. Weird how it happens right after putting on new tires. I guess everything worked in concert with the old tires and the new ones just rub differently.
