Haven't tried them. Just did a quick search...
"They use a internal leaf-spring mechanism inspired by vintage Alps SKCM Orange" Sound's very interesting >.>
Even tho medium-heavy would be preferred over medium-light, I will check them. Thanks for pointing these out!
Yes. You might want to get these while you can.
I think they were created by someone who is on this forum, and others.
The Gateron Melodics could be modified into a 'quiet-clicky,' which is essentially what the Lanes are. A quiet-clicky based on an ALPS-like leaf. It was possible to standardize the modification, and have Gateron produce it. [Which is a lot easier than modding x87 or so Gateron Melodics.]
People have found that, in order to obtain maximum tactility, it is best to use thin keycaps. For example, modern DCS.
I went the opposite route, and turned them into light-tactiles by using SA PBT. So the choice of keycaps does matter with these.
