I haven't had a naked bike since 1984! Somewhere over 65 the wind pressure gets tiresome.
So, it seemed I could not get a Flanker for months and I bought a Trend. It went on in less than 30 minutes (instructions are pictograms) and looks good. Weather's bad here, so I only got to ride it once for an hour-ish. I like it. Flanker may look better, but the Trend likely works better. Below 50 the wind hits my face shield and above the mouth vent so I don't get enough air flow to stop face shield fogging when temps are in the 30s. Over 60 it hits the top of my shoulders like Puig's wind pressure diagram.
The 2-point mounting ended up quite sturdy, mostly because the struts angle outward.
