They may not make you buy a case, but I just wanted to prepare you for what you might face. Just part of the fun of MYOG!
As an alternative, you could do short sleeves instead of pole clips. Just use a loop of webbing/ grosgrain, or create a loop out of doubled over fabric (helps use up the waste). Big Agnes did the fabric loops on their Seedhouse SL's a few seasons ago and it seemed to work OK (or at least I didn't hear any complaints). You would lose some of the convenience of pole clips, but would still save over full sleeves.
