As I mentioned in the Icon helmet thread, I have been wearing a Scorpion with a built in sun shield for several months and really liked it. Then one day I went out in my Shoei and realized how heavy the Scorpion was. So after a bunch of research I purchased a Shark Speed R on line. I took it out for a first ride yesterday, and so far I am impressed. It's as light as my Shoei and moves air much better than my Scorpion. The visors are both optically very clean. I rode in temps from 80-100F and was comfortable. I will have to wait a few months to evaluate cold weather results.
