This reminds me a bit of the Laminar Lip that I used on a previous wind screen (believe it was on a vstrom). It was quite effective but was held on with adhesive strips which I didn't like. Seems like there may be a couple of concepts here to direct air flow and to keep the flow "laminar". One approach, similar to that found on the Madstad, is to use a shield on top of another shield with a gap between to remove turbulence and achieve laminar flow. As far as I'm concerned, that is a proven concept. The other approach, similar to the Laminar Lip, is to shape the top of the shield so as to direct the air flow upward and hopefully, over the rider's head. With that summary, I'm wondering if the Phantom Flip could combine both of those elements in the design. To do so, I believe the Flip would have to overlap the stock shield a bit more. I really do like the idea of using mounting hardware to attach the Flip rather that some kind of adhesive or velcro. The concern I have there is whether mounting the hardware on the very top edge of an existing shield would provide a rigid enough base for the Flip. Attaching the Flip to the stock F6B wind screen might be OK due to how short it is. OTOH, attaching it to the top of a taller wind screen could be problematic. Referring to the Madstad for comparison, the base shield is very thick and robust and the mounting hardware is bolted on in two places, both low and high. This makes for a very rigid and robust setup. Of course, with that approach, holes have to exist in the base shield for mounting and I'm fairly certain the Flip attempts to avoid that. Anyway, the larger the Flip, the more rigidity of the attachment will become an issue, IMHO. This is where real-world testing can prove the concept.
