I opened it up and tried swapping in a red switch in place of a black, with the splash guard on. Sort of akin to what REVENGE said, it's not really that great in my opinion. It felt a tiny bit different, but somehow didn't feel at all lighter.
I finished it by keeping the splash guard out, since the novelty sort of wore down for me. Despite my claim of it feeling like a heavy Topre, I was missing a lot of keys (especially spacebar) because of the heaviness. I also switched the cord to come out of the left side of the keyboard, since there was a hole for it, so that was pretty cool.
