Titanium in the STM on the SX works perfectly for me
My traditional build in the STM was Kanthal A1 5 wraps of 26awg
Have done this in 26awg Ti & it comes in around 0.26ohms
Needed to drop TP to 300f && I could not wish for a better vape [disclaimer: until something else tempts me]
Vaped half a tank last night && checked the coil/wick after washing in hot water ... both like brand new, unmarked !
Expecting much fewer coil changes with Ti as more resistant to gunking
The wire needs slightly heating to make coiling easier as its quite springy, then it coils like kanthal but holds shape even better
Highly recommended
Gently heated till golden && stopped before too much blue appears, then pulled through wet towel to remove carbon deposits from torch
Coil does not move atall when wicking
