I've got the Imperial Blonde in bottles, trying to carb up right now. It came with 1.5 oz of Brewers Gold bittering (9.7% aau), 1oz of Argentine Cascade flavoring (3.2% aau), and 0.5 oz of Cascade aroma (7.5% aau).
It was also one of the most expensive kits (for what you get) that I have seen at my local HBS - $53 is what i paid (it wasn't labelled, and i didn't know how much it was until i rang out at the register).
It's not fully carbed yet - bottled on 1/20/10, but i had done a short stint in the brite tank to help it clear a bit, and i think that's what's causing it to take a bit longer than any of my other brews.
Taste has been ok - I'm not familiar with the style, so I've not got much to compare it with, but it's good. I wouldn't buy it as a kit again though.
