Would those be the switches in the Quiet Pro Keyboard? If they truly are "the world's quietest" as they claim then I might want to use them depending on how they feel. I do enjoy the feel of a tactile switch, letting you know where the actuation point is, but I found the sound of my MX Blue keyboard a little bit distracting. I'd also have to figure out where to get Alps key caps if I did use those switches. Cherry MX is certainly the easiest to obtain key caps for.
