I matched the settings Cigatron suggested and it was only slightly better, but hotter, and I prefer a cooler vape. I just don't get it, since the Titanium does not impart any flavor of its own, then one must suspect the cotton, and how much or little is used, but if that's not the case, then the design of the Subtank itself may come into question. But not everyone uses a STM. I keep reading about the great flavor folks are getting with the Titanium & STM, but I'm doing a direct comparison with identical tanks and juice, the only two differences are the Titanium/Kanthal coils and power mode versus TC mode. Sure is a MYSTERY to me. I want to love Ti, as I'm sold on its better potential health qualities over alloys. I guess my next test will be a nickel build, but I don't like its metal composition, though I'm not allergic.
I don't have or think Kanger has a pre-made titanium coil to compare to, but I did get good flavor with a Joytech Delta 2 titanium pre-built coil in the Eciggity/EHPro Morph tank I have, just adds to my confusion!
