Today in Victoria the winter decided to take a holiday and we had an unusually mild sunny day...though windy. This gave me a chance to try out the borrowed Lamina lip screen (thanks Michael).
Sue and I headed up to Mirboo Nth (which, by the way, has a terrific biker's cafe called "In-line"....closed in winter but opens again in August)
We did a round trip of around 130ks....not a huge ride but a good trial.
Here are some conclusion so far:
* The Lamina lip works!...we found instant results over the stock screen
* Buffeting was reduced dramatically
* I could easily hear the engine purring along, the only real noise was coming from the strong winds.
* I tested the above statements by ducking down under the screen and there was little difference in noise. I could also ride with my visor open which was terrific...as it was still possible to get a small amount of air into my face which in summer will be a blessing.
So pretty happy of course...Sue also found it worked really well for her as a pillion.

I should add that I have a basic flip face helmet which, whilst convenient, is a noisy helmet. Sue uses a normal full face helmet that also has a chin-skirt....which was my original helmet and much nicer ...think I will steal it back!
Drawbacks? Maybe looking down though two "bits" of screen but I didn't find it distracting at all....also...I didn't want to remove the lip from the screen as I was worried about the velcro dots coming off the main screen as it is only on loan at the moment...so it's hard to clean behind the lamina lip. The 3m velcro sticks like ....well you know....!
