The large one is on sale right now too... I might pick it up (my current mat is pretty narrow)...
Neither mat is going to be thick enough for burro or raahauge's. At Corona I had a blanket folded in half and the thiner mat on top and it still wasn't enough padding. You'll definitely want somthing like a yoga mat or thick piece of padding underneath the mat itself. I was sore two days later after a weekend of prone at raahauge's and burro is just like raahauge's.
