Best flavor I've experienced is on my magma rda and KFL rta. The magma beats it though!
My rebuildable tanks and drippers are;
Rta's=genuine KFL, genuine taifun GT, aqua clone, expromizer, Penelope, fogger v4 & v4++, magoo, ithika, aios and a few more I can't remember at the moment.
Rda's=tobh clone 22mm, tobh 28.5mm, magma, quasar, trident, omega, igo L
