I'm in Staten Island and I commute to Manhattan daily. It's almost a 2 hour commute on public transportation, and I go from a train, to the ferry, to the subway. It sucks. Anyway, I've heard a lot of good things about carto tanks here, and I'm currently waiting on an MVP 2 via vape mail. Figured that maybe I should try a carto tank on it, as it wouldn't be as top heavy as it would have on the iTaste VV v3. What's the most leak proof, easiest to use, least amount of hassle, tank set up you've ever owned? I do not have a way to really fix something on my commute, and as I keep everything in my purse I'd like to avoid leaking as much as possible. Right now, the Mini Protank II has been great on the iTaste, but flavor is rather muted then what I have ecperienced with the couple of iClear 16's I have. However, I can't really take the iClears on the commute as I've had problems with leaking. Seems that if they aren't kept on a completely upright position, they leak.
