I use two OG Cherry sets now, both are beige ones. The first is an ANSI 1800 set, the other set is a really rare, one with an XT layout with original mods with hat design. I am using the second one at work along with modern OG Cherry icon modifiers. This last is a very interesting set, that I am not sure if it is made of ABS, because the keys feel more dry than ABS, closer in feeling to PBT. I doubt they are PBT though, but I have been using it continuously for several months so far with no signs of shine yet, it still feels very dry to me. I know it came from a rare keyboard that was sold as part of a computer attached to some sort of laboratory equipment, I do not have any data on it though.
The classic ANSI set is now very shiny and it feels nice to me as the keys are very easy to type on, because they feel like cradles for the finger tips. Very nice.
The XT set is sort of strange as it feels more like PBT. I hope it start showing some shine by the end of the year so the ABS true feeling will finally revels. You right, I like shiny ABS thick double shots.
