You can say that again. No matter how hard I tried to roll my Hubba Hubba up tight, I would always end up with a "puffy" package. I think it's partly the floor. It seemed thick. Same with the fly. I just tossed mine at the end of my three-day back in October because it had what I think was mildew damage on the fly. The seam tape and coating on the fly were peeling off in many places, resulting in leakage.

Can you maybe find a compression sacks that allows you to roll and pack the tent and then compress it so at least the diameter is not so large?
