I "believe" not positive, but Topre bottoms out no matter what. I think I read that somewhere? But anyways your problem is that you have a fullsize!

You need an FC660C instead of that board.. I hear ya on the KMAC though! I want a Happy so bad! They make great boards! I am the same way as you though.. Just sold 2 of my Topre and got 2 MX. They are just funner! Clicky little fun switches with no dome, lots of keysets, lots of aluminum case options, plate options, led options, etc. I love my 45g Leo but for projects and fun stuff I love my MX boards! Welcome!
