Don't know what anyone else thinks, but a buddy of mine had a 2 man flip over Clam and switched to a Clam hub style pop up, and says he loves his hub style. Another buddy says the hubs break after a while on them though. The hub style fold up into a bag that fits in the bottom of your Jet sled. His is 8' square set up and about 60" to 70" long in the bag.
