Well , after much research I bought a F-4 Customs 16" clear with Honda vent installed. Perfect for me. Great wind, weather & bug protection. If you're going cross country I'd call and talk to the owner. Maybe get a full touring ( tall ) F-4 Customs. They're pricy, but I'm like you, really wanted to do this just once. Crystal clear, will not scratch. Still looks brand new.
From years of reading here about windshields, the consensus is that if you want to look over the shield, the madstad is the way to go.
If you want real wind protection, and since you do not wear a helmet, I think you should get one that you look through.
One of my shields is a Light tint Tulsa Tall that I have cut down to a reasonable height. It is what I use for cross country riding. It is only about $140.
The rest of the time I use a 16" Clearview that I have added a mini madstad shield to. Without the mini madstad, the clearview is annoying at freeway speeds without a helmet.
I'll try a pic for fun. New server, maybe it will work: Never mind - still no worky.
I got the 14" this year, and am 6', with a 30" inseam, and I also have a Mustang seat that sits me 1" lower than stock. Reading your stats, and with the stock seat, I would suggest going with a 12" or 13" shield. If I was to order it again, I'd order the light tint, not the dark. The dark looks cooler, but it's pretty dark.
I traded my F6B for a K1600B but still have my 2 favorite screens for sale: SlipSteamer in clear and opaque OEM screen for summer. I am your size and liked both screens for different seasons. You can have them both for $150 plus shipping. My K1600B now runs 2 screens: opaque shorty for summer and taller clear one for winter --this combination is perfect for all year riding likevwe have in NorCal.
Do yourself a favor and just buy the mad stad. That's what you will end up with any way. I love mine and there are many others that will say the same. Pricey but worth it.
I really like my Klockwerks 14 inch screen. I have no complaints when riding solo and together. I'm able to actually hear the stock radio now too. I could have been gone with a 16 inch at 5'10. I did lots of research and didn't want to buy several windshields before deciding on one. Good luck in your search.
