I've got one with reds, and no ping to speak of- but then it's my first mechanical, so what do I know. I will say that the cherry stabilizers are stiffer than I'd like- I definitely preferred the ones on the Novatouch I bought (I returned it and jumped in the Massdrop for an ES108 Pro w/ 35g switches). When said board shows up, I will discover what life is like with costars- but as far as the KUL goes, not something to worry about (afaik).
