Yeah, mint is a funny beast - doesn't act like any of the other flavoursI'm also finding the mint is stronger at higher wattages. I did a choc mint, 8% peppermint, 4% double choc, 0.5 koolada, 1% sucralose that's really nice in the rose at 20w, but if I stick it in the goblin on the mech all I get is freezing peppermint.
