They're from down here in NZ, so I imagine not many make it up to you folks
I use Pac Jade all the time. Most often as a bittering hop, I've used it in blondes, pale ales and, if I'm remembering right, even a wheat beer. It gives a nice smooth bitterness, and a soft citrus aroma.
I reckon it's a great neutral bittering hop for a pale ale. I've never used tons of it late, but I imagine it would be fine, but uninspiring in a single hop beer.
