Delay both some to allow for possible gusts. Better too much speed than too little once airborne.
Jim - the meterological conditions sound similar to what happened to Continental 1404 in Denver a few years ago, except this time they were at Vr. As you said above, with winds gusting as they were, would you hold her down for an extra 50 kts or so cushion to help in case you were hit by a microburst or cross-wind gust at Vr?
