I bought the Pneumo last year, I also had the choice between the Pneumo, Atmos and the Bell Sweep R. But in the end I decided on Pneumo since I felt that the Atmos was to expensive and I already saw some damage on the Bell just from being on the shelf in the shop (or somebody used it for soccer practice)

And I haven't regretted my decission, it must be the best fitting helmet I ever bought.
