anybody heard of microswirl edging?

Most annoying thing on Sprint, I have highest screen available & wind noise is still bad. I have added some rubber moulding intended for another purpose round edge, to break up air flow & wind noise is reduce by approx 30%. I read about microswirl edging available in US which is made for purpose and supposedly s**t hot, but very dear to order & ship to UK
Does anybody have any ideas or info on products or home made mods to reduced wind noise?

Forget the bike, get ear plugs. They work great when "er" behind start shouting SLOW DOWN :upthumb:

I have the Saeng molding that was the version before the new and improved or renamed and repriced Micro-swirl. It didn't make much difference on my bike. It may have moved the air flow up an inch or so at most. About 20 years ago, I put one of their Winglet air deflectors on a bike and it moved the air flow up a several inches. The problem is that the little strip of plastic and it's mounting hardware probably costs more than the windshield you would be mounting it on.
