Take a look at the AGV Horizon. I currently ride with this helmet. Has a drop down Sun visor, light and comfortable, built in place for Bluetooth speakers and Mic wiring. The airflow is absolutely awesome, and it looks great. Revzilla has a good video about it. Cost about 360 for it. Of all the helmets I have used this is my second favorite, but feature wise it's my favorite. My favorite helmet was a Suomy but that was for sentimental reasons.
