I've been considering using slatted racks. Currently I run 11 frames in a 10 frame box for brood though, which I believe means for best results, I'm going to need a custom slatted rack if I try it.

Anyone else try a slatted rack with 11 frames?

Anyone else care to post experiences with a slatted rack, good or bad?

Anyone try a slatted rack in the top of the hive (vs the bottom)? Seems like this might be good for isolating the top of the hive from weather a tad more (Of course I've got a full top entrance as well which most don't have).
