I'm 5'11" I run the stock windshield. And can wear my hat normal up to 60 after that I turn it around.

 

Just wondering what you have? Im 5'10". The stock black shield is so cool looking. It's a shame the wind smacks me in the forehead while I'm riding. Wish there was something with good wind protection that retains the cool factor.

 

I'm 5'11" and run a brawler solo seat which is lower than stock, been using a 6.5 clearview w/recurve in dark gray on trips, here's a pic from sturgis with it on.

 

I'm 5'9" & I had a National Cycle V-Stream 7.25" smoked screen. It worked great except that it was about an inch too high for my liking. I still have it & I'd like to sell it. If you're interested PM me. I think I put less than 100 miles on it. Still looks brand new.
To answer your question I have a National Cycle Wave on now.

 

5'9" - I run a 9" recurve

 

I am 5.11 and use the KW 6.5. I would like to try the 8.5 KW, but am not willing to pay the money for the 8.5. If interested in the KW, there are places that let you try them. I like the look of the KW, not everyone does.

 

I'm 6'3'' and have a 10'' Freedom Shield. It's dark smoke in color and and it's a recurve design. It's perfect for me, although the "cool" factor of the small 4'' windshield goes away with the higher windshields. However, somewhere along the way, the "cool" factor tends to give way to "function". Anyway, Freedom Shields has different heights and shades of gray. The best thing is that if you don't like it, you can send back!! $98 delivered to your door. freedomshields.com

I'm 5'10" I run the 6.5 Klock Works and am perfectly happy with it. I think it looks great. I tried a friends KW 8.5 and could not see over it.

 

I saw a KW on a used bike at my local dealer. I liked the look and would consider it, but it wouldn't work with my windshield bag. I would love to find something short and that works at the same time. I want my cake and eat it too.

 

I've tried a bunch of shields. Stock, 6" Klock Werks, 6" and 8" Wind Vest, SE Ultra shield, I'm 5'10" with a 30" inseam...

The only shields that worked for me were the SE Ultra shield, 9-ish inches, and the 8" Wind Vest.

Then I added some fork wind deflectors I found on eBay. I can run any shield and it's tolerable. Even the stock shield (but it's harder to hear the stereo on the freeway). The secret is stopping some of the upward flow of air under the fairing that causes buffeting.

I think the ideal shield for me will be the Klock Werks 8.5", but I have yet to want to spend the $$$. I like the additional stability the KW shield provides.
