Pace,
Aiming at the cloud you will fly a straight line, just not the one you want unless you have offset for drift then picked your cloud reference.
Looking at the initial post, shum is using a cloud instead of a ground ref point, it is actually using a ground ref point that will cause you to fly a curve as you will drift and have to adjust heading to maintain it, if you set your correct heading for drift this will normally be minimal, but a cloud could actually be a better reference or that reason, remembering of course that, unless at the same altitude the cloud could have very different drift from yourself.
On the weaving/lowering nose, IMHO there is actually LESS discomfort weaving - you only use 15 degrees bank which DOES keep the climb going (in most ac), and if you are not climbing on a set track then just alternate direction of turn each 1,000' rather than turn off and back on. I have had some very stomach churning pitch down and back lookouts done to me (usually on the pitch back up)
