By god cosmo kramer, you make a rolling take-off sound as though it's dangerous and not for the feint of heart!
It is a perfectly acceptable method of taking off that is required on almost every type of runway other than pavement...that almost always requires a less than perfect ("sloppy") lineup.
All performance data I've ever used has given both static and rolling figures and in most cases the difference in distance is negligible considering the runway lengths unless you're operating at the extreme edges of aircraft performance.
So to answer the OP's question from my POV: either is perfectly acceptable given the traffic situation and aircraft performance from the runway you are using.
