The only way you are going to get laminar flow with a falling long, thin
object is if it is falling end on. All other orientations are unstable.

And the only ways you can make it fall end on is either put fins on it
like an arrow or put the center of gravity well ahead of the center of
pressure like a javelin and make sure you launch in that orientation.
