Husby just got his nominal 72x20 BA Q-Core SL from rei in the mail today. I already have last year's model BA insulated air core (the maroon one). We blew them both up in the house to check them out and compare, and were surprised to find that the Q-core is narrower and even somewhat shorter than my old mat... maybe a half inch or more all the way around.
We're not petite but not exactly giant people either, and it's narrow enough that husby will be taking it back tomorrow and seeing what he can get in exchange. Needless to say, he's not going to jump on another BA pad unless he can check it out in person first.
