I haven't tried the T2 but I never had much luck with top coil clearos. One benefit of the Protank II, is the pyrex / no glue tank. No plastic taste. As a bottom coil, there is always the risk of leaking but I haven't had any issues and I use 70 / 30 mixes, which are pretty thin. Performance is very good and it has the grab and go aspect. Fill it and take with, no issues.
I rebuild my own heads so I haven't tried a stock head in a while but I'd stack the performance up against a lot of "average" typical genny builds and most genni's aren't really pocketable.
Thanks again! Protank II sounds like it might be good choice when it's time for me to upgrade without spending too much. I'll do some some more research about it.
