Was at dealership today looking for a new helmet for a Christmas present for myself. I kinda like the Bell Mag 9 because of the feature that allows the communicator to be integrated into the helmet. I was wondering if any of you wear one and how do you like it? Also, I didn't want hijack another thread but what is the real difference between the Sena 10 and the Sena 20. I have Sena 10 now and am wondering if it is worth updating if I got the Mag 9. Thx for your input.
