Dropping the H-Bomb (and I don't mean hydrogen) is a good way to kill a thread
Back to topic - as stated I'm in favour of staggered starts, but then I usually crash on the first corner and have very little control over the steering at present so that's probably for the best.
That said, for all I know, a GP start may be better. We could always give it a quick trial for a heat or 2 to see which is preferred if there are enough people curious about it.
