First, me being a smart a$$! Baggershield doesn't have a 13" windshield for the F6B. You are probably referring to the 11" Sport Shield, which can be raised to 12.25" (which is close to the 13" you talked about.)

Here's my two cents: I'm 6'3" and I LOVE the 11" sport shield in the summer. I did raise it all the way to the top 12.25". I get very little buffeting but also, a nice breeze that blows down my face and chest to keep me cool in the 95+ degrees hot weather in Texas.

I have replaced the the sport shield with the 11" to 19" Adjustable Shield, which is the 11" sport shield with a "rubber screw-on" add-on 8" shield. It works great in the winter months and when I want more protection.
