I have an RF-1100 coming from an HJC CL-16 too. Night and day. I know the 1200 is "better" but I got the 1100 for a steal in a clearance sale. I'll assume the 1200 really is better, and damn, the 1100 kicks ass. Can ride all day (put in a 12 hour day last weekend) with no discomfort, cooling air flow is great, and air flow around the helmet at speed is way better. Only thing I didn't like was the lack of pin lock shield, but the 1200 comes with one. I thought the wind noise is only a little better in the Shoei than the HJC, but earplugs solve that anyway. My Cardo bluetooth headset fits fine.
