you're a tall guy, i'm not. but either way, you will find that the stock hd windshield is less than optimal. i went with the lrs mako in 12''. even though it is 12'' and the stock harley shield is 12'', the mako actually sits up a inch or so higher. it isn't as 'laid back' as the wind splitter. it is also a little wider at the top. i find it works great. much calmer air behind it, less wind noise in my ears, and i can hear the stereo better.
being a tall guy like you are, i would recommend either a freedom shield or an lrs. either one of those companies can give recommendations based on your height, and if you order either one, you can try it (without removing the plastic covering) and if it isn't to your liking, then send it back for an exchange or refund.
lrs has a big sale going on right now where you could pick up a shield for less than $100, and i've never heard any bad things about freedom shields (other than a little on the pricey side). good luck, and welcome to the tank.
