I prefer the soft carrier too but I disagree on one point -- the wind drag. We've used both and I felt the wind drag was much more pronounced on the soft carrier than the hard carrier - perhaps because the hard carrier is sort of aerodynamic. Anyway, even with the increased wind drag, I still prefer the soft carrier because it's easier to store and maintain. Be careful, too, with the hard carriers. Someone posted on these boards awhile back that they bought a hard carrier used and installed it on their van and, because it wasn't specifically made for the van, it pulled the roof rack off and damaged the roof. If you do decide to go with the hard-sided one, make sure you get one specifically made for your van and have it installed by a professional.
