Not sure what anterth's path was, but my co-op partner made one from scratch that got us first place:
Suck My Kiss Co-op Path
Few opportunities for significant squeezing here, but there are a bunch of split back ends (basically anything where the SP runs up to one person's phrase can and should be split). I'm not sure about the solo activation since that's always going to be a bit of a crapshoot, but we had the most success with doing it as marked. Also, I've never hit the squeeze marked on the last activation, but it really looks like it should be possible and we never did get a good front end on it.
