I bought,from a DIY vendor,a bottle of 80vg/20 pg nic level 6 base with some sweet tobacco flavor..Great service etc...I have been lowering nic level over a period of time to 3/6 depending on vendor..This my first time DIY..I've never had a harsh peppery exhale with any premade e liquid..I tried adding VG I bought at rite aid,got a lousy taste,tried some from hobby lobby and same taste..I also got a smaller jug of PG but adding that still harsh..Maybe get a bottle of 0 nic and cut in half? Also flavor is too sweet for my taste..May try a bakery flavor..Using a Triton 2,.5 ohm coil at 40 watts..Same flavor with triton mini..Premade uncle junks JW 6mg. nic tastes great in both..I'm trying to costs....Thanks for any advice,Bob
