The standard missions can only really be used so many times before boredom drops in. There is the mission book, which is a decent alternative, but I still prefer the Ard Boyz mission list I have been keeping. Granted that the prelims this year were some of the worst of it, but if you add in all 6 I have from last year, and the 6 total this year... It all balances out to some very interesting lists.
If you are local, I may put together my mission packet for you if you ask. Two stores that I frequent will be getting copies if they are interested. Not to mention that I carry full print outs of these when I show up.
