I have to agree with the OP on this. I love my rebuildable tanks. Never will go back to stock coil types. But with that being said I always have some kind of issue with the rta's. Small leaks, the occasional gurgle, etc. None of it makes me want to go back to being a slave to the coil makers though. It is just something I've learned to live with until someone comes out with the "Nirvana" tank.
