I don't really have issues with wobble, the switches are secure enough with the two solder joints. I'd feel a bit better about them with 4 joints, especially when it comes to pulling keycaps, but I'm not worried about the build. I remember Delirious' post very well, it was a huge inspiration for me. His alignment tool was a great start but it was a huge pain in the ass to use. @karolus of Karolingian Craft recently designed a new plate-style alignment tool that fits over the top of the switches and keeps them much straighter. I used the new tool on this build and my half plate KFE (video coming soon!) and I don't have to worry about misaligned keys at all any more, 10/10 tool.
