Wow, you have a Mk6a? Lucky guy.
BTW Lerch, how do you find the comfort level of the Mk6? I have one and I find that there is a pressure point on the top of the helmet, mainly on the top of the suspension system where it's a piece of string going around in a circle (sorry if this is a bad description). I tried to adjust it's size and fiddle around with the suspension but overall I find it quite uncomfortable compared to most of my other helmets.
