I've been told to expect less vapor with my new pg only, as opposed to my old 50/50. The flavor and throat hit are there, but there is almost nothing to exhale. I'm wondering if this is normal, or if I should be concerned about a blown atty in my clearo or something? My battery is a new v4l titan manual showing a solid 4 volts on the multimeter, so I know I have power. Thanks in advance!
