The Coldsweat is nothing like the Evo, at least the 7 string versions. I replaced an Evo 7 with a CS 7. The Evo has way more upper mids and a bit less bass. While having about the same amount of treble, the CS seems more organic and less piercing.
From what I've read about the PK it should be as close to an Evo as it might get. Tim recommended me the PK when I asked him about a better Evo. I went with the CS because I wanted a more vintage vibe to it.
