The stock shield is fine around town or on short trips. Really, it did a better job controlling buffeting than I thought it would.
My main complaint is the level of wind noise from it. I know not everyone listens to music when riding, but I usually do, especially on long trips. It was almost impossible to hear the music above 60mph or so. Earplugs helped a little. But depending on how windy of a day it was, anything over 60-65mph was still a no-go for hearing music very well. Also, while the buffeting was fine for me, when my wife was on the back she said it was much worse than my '08 FLTR.
I ended up swapping out the shield for a 12" Freedom Shield. It is perfect for me (5'11", 30"), and my wife noticed a massive difference as well. After putting it on the wind noise was cut dramatically, and I could hear the radio very well up to 65ish with no ear plugs, and you could hear it reasonably well up to 75ish. I had already ordered speakers and an amp at that point (Hogtunes kit). Now I can hear the music just fine, at as fast of a speed as I'm willing to ride, without turning it more than 75-80% of the way up.
