Good luck on finding the right height windshield. I am 6' and sit pretty straight up also, I even use a backrest and I need at least a 9".

 

I met these guys at our local rally and the windshield looks great.
More flip than the Clearview
Thicker than most windshields
a little straighter (doesn't curve in as quick) on the sides, for more coverage
a better price and availability than clearview

He also told me he use to work for Clearview

LRS makes a windshield that is 15% stronger than the stock windshield and its at a good price. It only takes about 3 days to get you. The ultra windshield would work best for you, it recurves the wind about 3.5" above your head. I would recommend a 9" shield at least.
