Are you talking about these guys? http://www.longrideshields.com/product_p/lrs-taka-s.htm looks like they have a 24" recurve in a light tint for $189 and 2 vent hole options or no vent hole for the GL1800 which I'd bet are sloted, but could be used on the F6B, otherwise they have 7", 8", 9", 10",11", 12', 13", & 14" sizes for the F6B from $129 to $164.
Humm....very interesting, I'd like to know how the GL1800 24" performs compared to the Klock Werks flare.
