I dunno, I tried it with 50/50 and was basically drinking liquid so I don't use it anymore.

My xros arrived in the mail this morning, and I'm already having spitback issues with it.  Initially I filled it with some strong nic salts juice I had laying around, and this caused horrible spitback, however it's 40:60 VG:PG.  My sub ohm juice seems to be a bit better (currently running a mix), would finding some proper high VG nic salts juice help the spitback issue?
