Protanks and slight bad taste at the end

[withravenoushunger]

It seems to be like this with all my heads. It tastes fine until the end of the exhale. I always get a slight maybe burnt taste. I know its not burning or set too high. I only really notice this with fruity juices.

Same issue, but for me it tastes metallic. I get the Burt taste on refills. I gave up on protanks. My only hope is the mini protank. I believe on the mini protank we will be able to use an EVOD base, if so, that will solve all these problems. Just a theory of mine.
