Your post raises a question I have. If you look at Cl/Cd the 7037 foil beats the MH32 across the range. Why is the MH32 the popular foil of the day?
Don't know specifically why, but l/d is just one among several considerations depending on type of plane and its designed purpose, flying style, etc.

I've heard the 7037 has a slightly nastier, more abrupt stall characteristic. Also that the MH32 is very responsive to flap input, efficient over broader speed range, generally better at high speed, may be a better multi-tasker.
