PNW has a scaling club of it's own. Some teams that I've seen scale are 2557, 4450, 1983, 4980, 5803, and 1425. I know that 2522 is working on a climbing, but I have yet to see it work. There is also talk of 1318 and 488 implementing a climber to their robots, but we'll have to see.
Thank you! Here's a picture of the first (maybe only) PNW double scale:
