Got 'em today, and for the very fist time since I got the bike, I enjoyed what I would call a tolerable amount of noise, and no buffeting. This was with the stock screen and the TT mount adjusted all the way up, and leaning back as far as it can lean. There is still room for improvement for sure, and I'll still be tinkering. But, I can actually ride it on the freeway and, you know, enjoy it now
Side note that is a little annoying: I ordered my Madstad bracket on the same day I ordered these winglets. The winglets were not in stock when I ordered them, so the place had to make them first, then ship them. I did not pay any expedited shipping, etc. Oh, did I mention that they came from England? The Madstad comes from Florida. I paid extra for 2-day shipping. Florida is 3 days for me via UPS ground, but I wanted to make sure I got the thing as quickly as I could so I ponied up. I have no tracking number as of yet, and I've emailed them three times just to get someone to tell me that they actually are going to send me a bracket at some point, no response.
I have no problem at all as long as someone will communicate with me. Maybe they're out and have to make more, or maybe there is some other delay. No problem at all. But don't take my $150 and then just ignore me. That's lame.
