Ren,
That is an interesting question. Sorry I do not have the answer, but I will add this to your question: Assuming one of the two airfoils will have a better L/D ratio, I would think the better L/D ratio would be the best choice for both a low & a high ceiling.

Also, I do not understand your statement below. A 6% arch has a higher camber than a 4% arch. Is that what you are refering to? If not, what did you mean?

A smaller percentage would create a higher hump in the air foil increasing lift according to Bernulli, but yet it is suggested for a lower cieling. Whyis this?
What am I not seeing?
