Interesting find Thermin! I've heard of Content before, but never heard of KTT. For a second I thought they may be related to the KBT switches MK.com used in their early Disco TKLs, but after reading your write up I do not think the two have anything in common. Anyways keep up the awesome work man, I love reading the write ups & it helps keep me in the know with new MX switches hitting the market!
