I am 5' 10" and installed a Cee Bailey 4"X4" and am quite pleased. In the down position I can see over the windshield and the air flow goes just over my head. At higher speeds and colder temps I will raise the shield. It is much quieter than the stock. It took me no more than 10 minutes to switch over. In Minnesota where we have a little cooler air I expect that the extra width will be nice. I have and 05 and have yet to ride in cold weather. From what I have read from others this 4x4 has had good reviews with regards to noise, rain, and cold.
I plan on a trip to upstate NY and on up into Canada and returning through the upper Pennisula of Michigan in a couple of weeks; so I will get a chance to really test this machine out.
