I got around to brewing the recipe, but without Riwaka, so had this bright idea to use galaxy instead, then I had to adjust the hopping a bit and dry hopped with cascade only. Looks a little like this.

Got the keg into the fridge last night and I'm pretty pleased with it, a lovely resinous character, great aroma and nice balance. Maybe not a clone, but damn nice all the same.
