post trip Lip tip ...
I had my face shield mechanism fly apart the other day ... that left me to the mercies of the stock shield and a Laminar Lip. Lucky for me it worked pretty well. No direct buffeting to my lid but there was more than enough air to keep my glasses free of rain drops. Only downside I can foresee is when the rain gets serious and the temperatures drop. Other than a projected problem I'm happy with the Lip.
What the hell do I know?!?
