Hi the coils i make taste bad. Not so bad, just not good. not really a metallic taste, just not so good. i has 32g kanthal 2mm silica 3mm silica .99 nicrome. when i rebuild nova heads i dont use nr wire and it tastes ugly. Not so ugly, just not good. never tried it with nr wire except the replacement heads i buy are good cept for a few DOA ones. On my aga-t i tried silica wick and each attempt i spread out the coils more because it burns too fast for it to wick and i keep coil horizontal like most builds ive seen. just tastes nasty.not so nasty, just bad.
