I was about to start a thread about the same, the optimal freestyle wing, the variable airfoil tries to balance the tendence to tip stall because the taper (tip 60% of the root), all is about balance, for 3d you dont want the tip to stall, for pattern you need to do snaps that need tip stalling, so, the "ideal" wing can do snaps but only if you force it... best of both worlds.

Ps: With the data that you have post here I will try to reproduce that wing, thanks =)
