Im 6'1 with a 34" inseam. I just purchased a 14" KW and have only ridden about 10 mi with it. Still a little chilly in Iowa and the roads are still covered with sand. The wind just hit the top of my head.
I was riding with a KW that had been cut down to about 12" and was getting a lot of wind on my face. Even with the shorter version, I could still wear a ball cap at hiway speeds tho.
I would think that a 16" would work well for you. I also ran a 13" CBaileys for a couple of months that worked fine but I like the looks of the KW better. Watch the classifieds and Ebay, you should be able to find used for about half the cost of new.
