Y o u guys ever consider flip up's? The wife and I have matching full-face-flip-up's that work great for our purposes. They tend to be a little noisier than regular full face in direct wind, but with the windscreen it's not that noticeable. It's just more convenient to be able to toss the front of the helmet up out of the way when you want. They also have built in sunglasses that slide down from above.
Modular's are great, especially for communicating at a red light. But, since we're going to have comm systems, I wanted a queiter helmet and figured the best thing would be a full face.
My wife's bike only has a small windshield too...
I have a Nexx X30 right now (it's been discontinured). It's light weight, and you can ride w/ the face shield up if you want to. But, there's no room for speakers. They saved on weight and the size of the helmet by putting in very little padding (almost none). Still a really comfy helmet though.
