The C6.0 is a very exciting development it sounds like. The Hed patent has expired I believe, does your rim actually bulge or are the rim walls just curved?

As far as the frame goes, I think unless you can do the following don't put another TT frame on the market:
1. Aero shaped tubes. i.e. blunt leading edge and sharp trailing edge.
2. no less than 2.5:1 tubes, no wider than 30mm on downtube or seattube.
3. Aero seat stays
