your watts?

Yeah like the other guys said, too many variables. Having said that, I oso own sig75w. On zephyrus 0.7 ohm build, 25w I need two samsung 25r a day. I vape a lot that's why hehe. Battery drains faster on tc mode I notice.
Sigelei is producing 75w v2 that supports bigger sized battery (fatter than 18mm diameter) maybe because of this battery draining issue

Yeah battery level goes down when firing button pressed. Happens all the time on 'high-ish' wattage. But on my other build 1.2 ohm run at 15-20w it doesn't jump down

depends on ur setup.prefer single batt or dual? tank? subohm tank? dripper?

rokok elektronik@john got shop now. Vaporhub.nearby mines. and downtown mines already closed and moved to sri kembangan behind giant.
then u just need to bring extra batt, why dont u try ipvd2 or sigelei 75?

VTC doesn't work well with Titanium wires. You can ask firestonez. Sig 75 has poor battery life.

Nichrome, imo same as kanthal minus the metal taste you'd get at the beginning. Titanium, nickel ni200 for TC. SS 316L is the best again, imo, clean taste. 317L also for TC at half the risk of ni200 and Ti wires. Oversimplified but you get the idea.

Definitely get 26g first. It's the most versatile wire gauge to work with.
Guess if that were my only option, I'd go for Smok since, "ooh purrdy lights". Like Vail I'm too a Yihi fanboy.
