Have the Schuberth C2 and a work supplied Caberg, miles apart from each other, the schuberth is comfy and I can open one handed, plus it has the city visor thing. The Caberg is impossible to open as the catch is so stiff, plus I found it uncomfortable over distance, not a bad budget lid I suppose but I wouldn't pay for one with my own money. The Caberg is easy to fit comms too, the Schuberth a pain in the arse. Schuberth is comfortablle at motorway speeds with out ear plugs the Caberg is very noisy. But it's the difference between paying £140 and £400
Have had a Caberg Justissimo flip for nearly 3 yrs now and I am constantly surprised as how good it is for the price. Mine flips open fine with one hand, doesn't leak in rain (3 hrs downpour in the motorway and not a drop), can ride at up to 60 with it flipped up (don't do it for long for safety reasons) and the sunshade is great. I also think the finish and comfort is fine. Negatives? It's noisy (but quiet compared to my Tour-X ) For £149 and in matt black it's a great helmet. But if I were to get another flip, I'd be tempted by the new Shark Evoline which flips right back over the helmet and looks great. Tried one on, seems good and priced well - any experience??
BMW will sell a double glazed vizor which cures the misting. There was a picture of a new system 6 on here recently which appears to come with double glazing and flip down sun vizor.
