I feel that it's too expensive as-is for someone with a modern 87-key.
I'd prefer to see you add the 7 R4 1.25 mods to the base kit, or remove the 1.5 mods (and potentially roll them into CMYK V2 as an additional R5 option). From the perspective of someone with a modern TKL, I have to pay an extra $50 or so to get the 7 keys I need to make it work on my board, and that still isn't quite the same set as I get with a winkeyless board. I'm also not sure why 0/ins is still in the base set after the splitting of the numpad. If we're going to split the numpad anyway, is it possible to get two numpad enters, one with the vertical legend and one with the horizontal legend?
I appreciate what you're trying to do here, but it feels like you're catering specifically to the winkeyless TKL users, who aren't enough of a majority to carry a GMK buy to MOQ, particularly not to the larger numbers you're throwing around now.
