Never had Union Jack...looks impressive.
For Surly, I can get all of the year round series, Furious, Bender, CoffeeBender and Cynic. Some of the seasonals could be difficult, I can still get Hell, will be able to get SurlyFest, it should be releasing soon. Wet won't be released until October, but I should be able to get that. Abrasive won't hit shelves until around December I think. Darkness and Smoke however will be a tad difficult...most stores around limit customers to one bottle because they only get 3 or 4 in the whole store.
If you want to talk a little more value....I do happen to have an extra Surly Pentagram, or "5"...its their 5th year anniversary ale. Brett fermented...red wine barrel aged, cost me $27 a pop. Really cool bottle too.
So whatever you need, provided its released I should be able to track down. I'm lucky enough to live close enough to the brewery that most of the surrounding stores have a pretty big stock of Surly.
