Unibroue 17 clone?

Hey, all. I'm totally stuck on Unibroue's delicious "17". Problem is, it was a limited release, brewed only once. Supplies are dwindling, and I think it's time to begin working toward cloning this sucker so we'll never have to be without.

I'm not any kind of experienced recipe-formulator (I'm only on my 4th batch of homebrew overall) so I'm not really able to even make a stab at it. Anyone want to try?

FYI Unibroue 17 is back on the shelves.
