I was debating between the Bell Super Air R and the Bell Super DH and after talking with the Western Bike Works Customer Support, I went with the Super Air R. The CS rep took the time to talk about my local conditions, type of riding, and provided great answers to all my questions. After the fantastic help from CS, I went with the Super Air R and feel like the CS rep's advice was perfect. The helmet has been great, being able to remove the chin guard while climbing is perfect for the SoCal heat. The large number of air vents are well positioned to allow great airflow with and without the chin guard installed. The helmet ships with a thin set of cheek pads installed and a slightly thicker set in the box to allow you to dial in the fit. Sunglasses fit well for days when you don't feel like wearing goggles.
I use the helmet for all types of riding and the removable chin bar is really helpful so i can use the helmet for casual riding and clip the chin guard on when I go on more intense rides.
