My girlfriend and I are debating on whether or not to pick of two of these, either the 20in ones or the 25in ones depending on whether or not we feel we need a wider surface. Regardless of matters, does anyone have any experience with these or have you heard anything about them? They appear as though they are the older verison of what is now Big Agnes Air Cores.
