Hello, geekhack! It is nice to join such a great community.
I'm using Groove87 with Cherry MX red, which is identical to Quickfire Rapid. Mine is with the silver housing and white PBT keycaps though. I also have a black one with brown switches.
Recently I'm interested in Topre capacitive switches so I'm looking forward to buying CM Novatouch TKL. Especially this will be compatible with Cherry MX keycaps.
I can see a lot of projects going on here and I love to participate.
