Deck's keycaps are hard to place. Technically, one could consider them double shot, but I feel it's better to emphasize that they are primarily PBT. The actual surface you hit with your finger is PBT, only the "skirt" is ABS. I believe they are dyesub PBT, which is pretty excellent, with much better wear resistance than ABS. Also, only in very rare circumstances do I prefer the texture of ABS over PBT: it's really the best.
I'm impressed with how fast you are adding inventory.
Also the box of the CMstorm QF rapid in Red shows the gray keyboard of the other styles, at least on mine.
Speaking of which, I got out my new CMstorm QF rapid (blue) and it also has 6 key rollover. Maybe only the very newest ones are NKRO over USB?
