Since I'm in the process of acquiring a Vee, I was wondering how folks choose their brain buckets. My older helmets were for closed cars, no aero or anything. The few times I drove friends sports racers, above about 100 MPH the lift on the helmet was pretty heavy.
So since the SA 2020 stuff is coming, how efficient are the various duckbills and spoilers on helmets? The ones with extensions under the front, for example - are you usually so far down in the cockpit that doesn't matter? Do is it a good thing? For helmets with upsweeps on top, are they any better than Supergluing some plastic strips or vortex generators on the helmet?
Of course, I'm talking about a Vee, so unless I somehow end up at Daytona maybe I don't need anything fancy? :-)
