TV makes good products but personally havent used any of the oil-based products. Would the Dart or Rev be capable of those above feats??? from someone who has used it?
Well actually I've used several of the line, and yes it will do it (or I wouldn't bring it up....) with the possible exception of 'holding a day's worth' which is, IMO largely under your control. It will do .1 a loading routinely. That's about twice what I'm likely to use in a day, but I know guys that use that much (and more) in a single nail hit. They tend to not be at the 'tiny hit' end of things, however. Would you be happy with 100 mg of PG? FWIW it's really less than a minute to reload, for most guys probably more like 15 or 20 seconds (dip the DART tip, put it back, done).
But yes, it does light vapor (as well as heavy), comes in 3.7 Volt versions,
never leaks (if you don't seriously flood it),
never clogs and is quite happy to dispense PG all day long.
AFAIK, it's the best match for your needs available today. Your call.
