Wow, great responses everyone and thank you for the information. I can see from the photos there is a huge difference between OEM and Cherry profiles! I don’t think I want to go the route of mixing them up. Indeed, from looking around it appears nearly everyone is out of the Ducky PBT keys (in the colors I want like the light blue). The double-shot white and blue ones on Mech Keyboards site looked really cool, but those are sold out! ugh
I suppose I will stay on the lookout. It doesn’t have to be Ducky, but preferably the OEM profiles for the closest match.
