The AEK II could come with wildly different switches (including even Mitsumi switches) depending on country of origin, date of manufacture, etc. I think Matias was probably targetting the SKCM cream damped switches, specifically, when creating their dampened tactile switches.
Do you find the dampened tactiles to be scratchy at all? I have found some boards with them that feel relatively smooth, and some that feel scratchy (mostly newer ones, including brand new). There's the obvious thing with wear, but it seems to be more than that. I'm starting to wonder if the reason may be that the older ones literally had many slightly different components. I swapped clicky guts into a mini pro just this weekend and I noticed that the gray sliders were a different shade from the latest production dampened tactile sliders (maybe just yellowing with age a bit), the contact leaves were made of a different material and/or had a different finish, and that even the springs had a different finish. The modern clickies and linears are as smooth as glass, and the same sliders feel smooth with the clicky leaves. The tactile leaves feel smooth with the undampened sliders. It is weird as heck.

I'm sure they must have been targeting the cream damped switches, but they really failed miserably, in my opinion. They made a decent switch, and I enjoy them on their own, but they're kind of crappy when you compare them to a real cream damped switch in an AEK II. I've owned quite a few AEK IIs over the years, including a brand new one back in 1990, and I've been lucky to have never had a switch get scratchy.
I don't ever keep two keyboards on my desk, but I often have two keyboards at my desk. Sometimes I can't decide if I want to use a Topre or a Cherry board, so I have a couple of options. I'm sure my coworkers think I'm nuts for constantly swapping keyboards. I used to use an AEK II with an iMate at work, but now I sit by a window, and I don't want my last remaining AEK II to yellow more than it has.
