<I think a single giant comb like that is pretty dangerous. Its prone to collapse unless you leave it alone with its attachments, and you can't really do that can you? You must be able to remove the comb, you can't view it from the side for an inspection.>
As I have stated in the past I like to run large volume TBH's that make very large comb. The only attachments I see is when they are heavy. I cut the attachments and as long as I handel them gently I have never had a comb fall from the bar I don't have any problem inspecting. I just put it back on the attachments I cut and the bees do the rest. I have never had a comb collapse yet and all I did on the hottest days was prop the lid and pull the back bar.
