I am only 5'10" with a 13" . Stock seat,hand wings. I cant get the wind totally over my head in any position. Put hand up and air hits me at forehead lvl. Ill try a few more positions but i am just not seeing the same results you guys are talking about Also some wind banging into my ears when i used a small helmet. And to be honest the passenger gets lots of wind. I was about to pull it off and put old shield back and ship it back. Ill try it a little more this weekend. My last try. I could probably see over a 15" all the way down but i don't want to try another if the 13 doesn't work for me
