I am kind of surprised that the provari is still a good mod, I have never seen anyone else carry one and very rarely do I see a tube style. Its not a cheap device so I am glad it is still a contender.
To be clear, it doesnt get jammed on the mod, the baseplate gets jammed to the
tank, and you literally HAVE to unscrew it there to rebuild.
I found the Lemo 2 RTA online for 27 bucks, seems like a deal if it turns out to be as good as supertrkr states.
Good tip about the Rayon, might give that a shot if the new tank seems to struggle with that issue as well.
I replaced all of the o-rings and gave it a good cleaning trying to stop the leaks last time I decided to troubleshoot the problem. I no longer trust the tank, its going to dump brown oil on my work clothes on occasion.
