I am 5' 10", have the 1" BRP riser and wear a full face helmet. I find the Givi is a big improvement over the BRP tour. It reduces both wind noise and lift under helmet. We use the Chatterbox intercom and the Givi has made it easier to talk. At $134 Givi is about $50 cheaper than CalSci, but Givi comes in just one size, 22.5' tall. CalSci ofers different heights which allows for more personal preference in fit, provided you can pick the right one. I think most replies will agree that the best way to get rid of more wind is to go taller. Givi is not perfect and like all screens is a function of your height, your risers, your helmet and where and how you ride. Most of my riding is non-freeway so I am willing to put up with some wind on the freeway as a trade off for looks. I am very happy with the Givi compromise between looks and function. I just can't get used to the looks of some of the big screens. PS: Both Givi and CalSci need clutch lever adjustment to avoid contact.
