I'm wanting to update my helmet, but will likely need to resort to mail order to get what I want in the size/color I want. I like the Lazer Helium, but find that according to their sizing charts, I am either at the very top of the Large or the bottom of the XL (with my cap on, I am right at 61 cm). The sizes don't overlap according to the size charts posted at Lazer. So would I be better off being at the small end of the 61-65 cm helmet or the large end of the xx-61 cm helmet?
