The Hubba, Hubba Hubba and (dare I admit I own one?) Mutha Hubba all have Easton aluminum poles; I can't imagine that the HP series would be any different. By the way, the Mutha Hubba is definitely a car-camping tent.

The Seedhouse SL2 is about a half pound lighter than the Hubba Hubba, but it only has one door. The HH has 2 doors and 2 vestibules. I guess it depends on the features that make it livable for you; neither tent is overly heavy.
