Just ordered from Revzilla Monday and arrived today. It comes with clear AND silver RST shields, but I took a chance on the red RST shield and was not disappointed. Fit is a little more oval front to back than the Airmada but not as much head room as my Shoei GT-Air; 2XL Airflite is a little more snug than the XL GT-Air. I wanted something a bit patriotic; I got it. Shield has no detents- it's either open or closed, but easy to swap. Internal drop shield hits my nose but it's manageable; most people will like it. Ventilation is good, but I don't notice it coming in through the vents; I think it comes in around the shield and from underneath. It's comfortable, moderately quiet (I wear foam earplugs all the time anyway), head check is really good as is all visibility. The internal shield and red RST shield is a good combination but there are all kinds of reflection artifacts when using the internal with the silver RST shield.
