Smallfly - The airfoil on the Ecstasy is completely different from the HB Mk III. It is more in lines, or resembles the Aeron foil, but since the leading and trailing edge, as well as the thickness is tapered (triple taper), I don't believe that it will be anything like the Aeron's foil performance.

Regarding Indy Trip - I still don't know about whether it will happen or not. This trip is for training purposes and is only schedule for Sept 23 thru 26th. I will let you guys know one way or the other.
