Well I finally finished building Sigma #2. This time around I used some new 65g Zealio switches and i'm sorry to say that I'm not very impressed by them. I find that they are very unstable and wiggle too much in the Gateron shells. The crystal clear look is very nice though. I'm having a little trouble with the LEDs touching the keycaps, but otherwise it's a very nice board. The Alu example is still better, tho. When I post the video, this will be the post that I am writing.
I think this closes out the project. Thanks for looking!
