This is just my personal opinion,
As someone on the "extra" list, I think the fairest way is to go the random route. I was not active for the GB, and missed it. I think that to be given the opportunity to buy a set, is great. Just because I had my name in the hat before some people on the list, doesn't negate the fact that we are all late to the party and in no way entitles me to a set over someone else in the same position.
Again, just my .02
