Rather than go for the Comet (and the associated time delay and the extra shipping/duty/tax costs to get it to the UK), I went for a Puig bikini cowl (self-painted).
Looks much the same and, I imagine, has the same wind deflection 'characteristics' as the Comet and any bikini/cowl.
At motorway/highway speeds....
Yes, more wind at the throat/shoulder level.
Yes, more noise in the helmet
Yes, a bit more buffeting than without it
But below 70mph, the above 'negatives' are not really there so a nice addition for riding the back roads. Looks dang fine too.
And truth be told, above 85mph, you're concentrating on hanging on too much any way.
