The fluid flasks rather nifty, but the tank is still plastic. I've been eyeing the Ion Legion map tank that altsmoke has along with the phiniac tanks. I'm really just looking for sleek, solid, pyrex tanks that I may not have seen previously before I drop the money on one.
I posted in this sub-forum only because it seemed like I would get a better response since the carto tank sub-forum has been filled with threads about Protanks whenever I check it.
