I know of a few modded switches I’d describe that way.
The Heisenberg is an Ink Blue with a Halo stem; think of it as a more aggressive Holy Panda minus the distinctive HP sound.
The PB & J is a Dragonfruit with a U4T stem; kind of like the previous switch but with extra-short travel.
In general, the Halo and U4T stems are my go-to when I’m chasing that D.
