Oak, did you run your marathon in the Nathan vest/pack or did you use aid stations?

After all your positive reviews I'm thinking of getting one. I use a Camelbak and don't really notice it anymore, but that means noticing it EVEN LESS would be super awesome. I only need to carry a gel flask (and/or packets) and my phone, sometimes car alarm/keys.
