I used 50/50 juice in a Triton V2 the most.  I've also had 70/30, 80/20 and max VG in it but never less than 50/50.  Never had a problem at all.  No leaking or spitting or wicking issues. I used the .5 ohm Claptons, which has amazing flavor.  Hope that helps.
I even use 50/50 in the Cleito actually.  Only had a leaking problem once after shooting the juice in too fast with a unicorn bottle.  It wasn't right after that and decided to just change the coil and am back to having no issues.
