Wow, this is really thoughtful, specially since you understand how it can be very hard to afford a CC Skull at the ongoing prices.
I would really love to own a MX Skull since I don't have one for a couple of reasons, 1. I got in on the last 4Grabs, was the first one to know infact, however since someone else (I won't mention who, unless they want to reveal themselves) really really wanted to get a CC and that person had been very generous to the community, I decided to give my CC spot to them, it was a hard decision to take, but I really felt it was the right thing to do at that time, and still do.
Second reason I want, and want the HO is that I have been working to make the 40% SmallFry board come true and made a case design for myself as well that can be used to carry the case, thus it is something I will most definitely use, and this as you suggested yourself nubs, would look great with the Nathan set, which would be going on my 40%, when that happens.
And I am not going to be selling this, reason is I don't think I will be able to afford another one, so I want one skull, really in any color, and I would cherish for the rest of my life.
