As I recall, you have several windshields, right? How tall is the National, compared to any others you've tried?
I ask because although I'm pretty satisfied with my KlockWerks Flare, for the pretty small price of the V-Stream, I'm thinking about giving it a shot in the Spring... but only provided it's a definite "look-over" windshield (for me, 5'9", 30" inseam).
