RIDE FREE/RIDE HARD/RIDE OFTEN
Congrats on the new F6 and welcome aboard. Windshields are usually the first thing to get replaced. The height you end up with will depend on a lot of factors and how tall you're willing to go to get protection versus how cool you want the bike to look. It's a compromise.
There have been quite a fee members that ended up trying various height shields before they got it just right. Personally, I knew I wanted the most protection available to cut out wind buffeting and noise so went with a 19" vented Slipstreamer that works great for my needs. I'm a fan of function over form. The Klockwerks Flare shield seems to be a popular choice that looks great and still provides a good amount of protection.
Welcome aboard. +1 on the Madstad. I have the 15 inch, look over the top by four inches and have zero buffet.
