I read a neat Aero Helmet study which showed that for the Giro, the Bell and the Spiuk helmets, when they were reversed on the rider, that is the tail was put forward, there was a 4 to 6 watt savings on drag.
they tested 7 riders at various yaw angles.

one of the issues was getting proper fitness with the helmet straps but for most it was achieveable. one dude ran long velcro bands from one side to the other, and another used masking tape.

i guess with your head angled down a bit, it helps air come up and get well off your back. after all, you either want air way off your back, or right on it. might be interesting.

i htink i might be able to get that to work with my LG and the GIRO, but that Uvex, no way.
im gonna give it a shot tonight.
if anyone else has any luck, post up some photos of how you got it to stay.
