I always questioned the idea of starting the ground roll with the
spoilers open...but at least the guys who do that have their left hand
on the spoiler handle.

15m guys do it too. It's basic survival in some std class ships, but
it also aids start of launch roll control in my ASW-20, and I've seen
plenty of 27 guys do this as well. Various aerodynamic "theories" as
to why this is effective are not very satisfying, but it's clear the
technique is effective.
