Not a fair comparison, but I had a 10" WV in gunsmoke for the last couple years. I always knew it was a bit too short, so I got a 12" Freedom Sheild in light tint.
Big difference for me, but that's probably because of the fact the Freedom is a 12". But, what I do like better about the Freedom is that it is excellent quality, it's thicker, and the curves and lines look great for the size of shield it is, and flows nice with the shape of the fairing. The WV with its smaller size and dark tint looked cooler, but no regrets since the Freedom still looks good on the bike- just not as cool looking, but I'll take function over form this time. A bonus is that it comes with it's own trim piece that is textured to make it look like it's made out of leather, and it comes with it's own wellnuts.
It provides the proper wind protection for me- I just tested it out on a 300 mile ride this weekend including some rain, and it's a keeper.
