I'd like to hear from anyone actually making and/or using styrofoam hive bodies.

What do you like or dislike about them?

How would you improve them?

Have you noticed excessive bearding in the heat of summer?

Can you pry them apart without damaging them?

I make all my parts, it's about time to start formulating plans for next year, and I'd like to make some of these to try out. Foam is getting to be cheaper than 1x12, and I think the insulating merits of foam might make them viable if properly planned and constructed.
