"I'm curious, what type of top entrances do you (and others) use? Details?" This is what I use: http://betterbee.com/products.asp?dept=1562 The entrance comes with a plastic plug to close it off. I also use a vent box over all my inner covers. Basically, an empty super box. Some have screened vent holes, some don't. I think it acts like an attic, serving as a place for hot air to rise in the summer, and as a buffer in the winter. It's also an overflow 'safety valve' in case a hive booms while I am away - the bees have somewhere to go besides the nearest tree. And, it protects the 'over-the-inner-cover-hole' feeders I use.
