I've been reading all of the posts concerning Pierco et.al. and thought I'd throw my two cents worth in, as my results were not as favorable as those replying thus far. I started with mediums in extracting supers three years ago and the bees seemed to work them very well. The only problem I had with them was the sticking of "top and bottom bars" which made separation of supers difficult, and sometimes stirred the ladies up more that I wanted to as I pried the frames from the bottom of the super I was removing. I could live with that. My problem came in using full depth frames. The bees would rather swarm that work the frames. I used it in splits along with feeding and I left it on during the nectar flow. I don't think I ever used a whole HB as a honey super during a flow (get too heavy for an old guy), but all in all I found them much more difficult to use than wax foundation. If they drew it at all, they made more cross comb that anything. I finally gave up and had a great $300.00 fire. Believe I'll stick with wax for now.
