Thanks for the responses. All my bearings on the bike I'm currently riding were packed last spring and the wheels were repacked in late fall using a general purpose automotive grease. The BB is a UN54 so whatever is in there is what I'm stuck with. As mentioned, I'm building a Plan B/trail/winter bike and that is where I'm considering using a cup a bearing BB with lighter grease. In fact, I may switch over to using Super Lube silicone based synthetic grease with teflon for all my bearings as the search I did revealed good reviews on the product. I see Ben4345 is using it. Anyone else? Any reports good or bad?
