I had never thought to try Wilamette in an American wheat beer, mostly because I associate it with an English sense of beer styles. To be fair, I've also never brewed with more than 20% wheat more than a handful of times (usually with German ingredients but sometimes with Centennial or Cascade).
Wilamette is a go-to hop for me in conjunction with Centennial or Cascade for "throwback" pale ales at all stages of the boil. I was not surprised to find that combination used in some of my favorite groundbreaking US pale ales from the 1980s.
For English style browns, bitters and stouts I tend to order English Fuggles because, while of similar origin, the growing conditions and generational changes make English ales taste more authentic with UK Fuggles rather than substituting related American hops like Wilamette.
That said, I think it's great that you gave this unique wheat beer combo a chance and shared it here.
