I agree about the wind, but look at it from a slightly different perspective. If I am using a fly, I prefer there to be *some* sort of air movement in order to minimize condensation from forming on the underside of the fly, then settling on my bag, heightening the potential to be colder due to the damp.
Does your tent have a fly/ground cloth combo option? I've done that a few times this summer, with good results.
