I see what you're getting at... I did plan on eventually doing a full Kamm-back to maximize aero benefit, but I need 6' wide sheets of material (not even sure what I want to use)to work with, and I can't even find it without ordering a bundle... I however, do have the stuff to try the VG array for now once I get some tuft testing in and determine proper placement...

My above thought was that the HPT software/hardware runs $500+, so that would be a pretty low ROI...
