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.
