I have a Davida Jet and I absolutely love it (when riding the bike).
I have been using it for about three seasons now and have become so accustomed to it that it's the one I reach for out of the cupboard over and above my Arai full face.
However, they are incredibly compact and light so I think they would make the perfect M3W helmet, as the head gear does not need to be road certified.
Combine one of those with some classic oval Aviator goggles by Jeantet and the overall practicality and visual effect would be perfect.
I agree that Davida helmets are beautifully made, but as for the "perfect visual effect". . .I tried it once with the goggles; looked in the mirror and all I could think of was Mutley!!
