Classy as it is to reply to my own post, I've been using the sh_t out of the opal hops. Mostly late additions, some first wort hopping. They're actually very nice. You get a slightly lemon, bright, spice smell with some grassiness. There's a floral, grassy, spicy flavor that comes across.
I tried them in a saison and a few tripels. Mostly in conjunction with Willamette or Saaz, both of which pair rather nicely.
They would be outstanding in a kolsch, helles, wit, wheat anything, tripel, golden strong, belgian blonde. They mate well with estery and phenolic Belgian yeasts. I don't get much fruitiness from them at all. The lemon is not a fruit salad. It's just a light lemony thing that you can smell if you look for it.
If you consider hallertau, tettnager, liberty, mt hood as an addition, you could easily swap it out for Opal to get a different flavor. Good hop. Wish I could find some 2012. I picked up about a half pound of 2011 that I just used up.
