I have done coast down tests at 16-17 mph with consistent results on a measured grade.
It might be better if we can see what you have already done with the coroplast.

Stable in crosswinds is a function of the lateral centre of pressure location versus the centre of gravity (on a bike - you). It's why all streamlined (eg land speed) motorcycles have a fin at the rear.

If the comment about damaging reputation is directed at me, you're using a very poor analogy. Or would you rather see misinformation being spread?
