I'm a big fan of the design, made a few up for nucs this year and decided to change the design up a little. I've used dual ladders in the past, Don puts them on the end, but I figured since the cluster is more center oriented at times why not let them access it right above them. I also got rid of most of the wood on the ladder since soaking in syrup generally led to nasty wood. The screen is a single piece I cut to length and staple on. The bees don't seem to mind it.
