they sound as light as browns then. or are they even lighter than browns?
The experience I have with "reds" are modified blacks, i.e. blacks with the light spring swapped in. So I might be completely wrong, but let's just suppose I wasn't.
I think they're lighter than browns, for they have no tactile bump. They might be quite exceptional switches if you can get used to them, but I think they're a bit too light to press. With browns, the tactile bump keeps you from accidentally pressing keys all the time, but I'm not so sure with reds ... the board they were swapped in is currently a bit disassembled, and since it doesn't feature any pointing devices, I'm not all too eager to use it as a daily driver. I suppose all hope is lost with me, keyboards with integrated pointing devices are just perfect. It's a shame the pointing stick on the Endurapro is so crappy, though.
