The best windscreen set-up strictly for wind protection I had on my '04KRS was a stock GT screen W/ a Laminar Lip. I am just 5'9" and I personally think anyone over 6' would be pushing the limits of the Laminar Lip.
Conversely the worst windscreen I had for any use on a KRS was the stock short shield W/ a Laminar Lip. Go figure!!
A short Ztechnik shield worked great in the summer. Very smooth air flow over your body.
, almost as smooth as no windscreen at all.
