Do you like mechs but hate how slowly they ramp up? Well, here's a trick: build coils with Ni200. You'll get instant vapor production, a sort of temperature control, and a better vape when the battery starts to sag.
Here's what it's about:
Nickel wire increases in resistance as it heats up. What you want is to find out the target resistance of a cold Ni200 build, so that when it's hot at the temperature you (ideally) want to hit after it ramps up, it reaches the resistance you'd normally build your atomizer at with kanthal.
With such a build on a mech, what happens is this: you hit the button, the build is cold and the resistance is very low. The battery initially dumps a lot of power into the build and the coil(s) heat up in a hurry. As the build warms up, its resistance rises, the power tapers off, and the resistance eventually settles roughly around what you'd use with kanthal. In other words, it's a pre-heat feature.
In addition, the hotter it gets, the more resistive the build becomes, which naturally limits how hot it gets somewhat, giving you more time to "feel" a dry hit coming.
Finally, as the battery sags and its voltage drops, the build gets less hot, its resistance drops also, thereby pulling more amps out of the dying battery. The vape gets wimpier over time just like with kanthal, but you'll use more of the battery before you feel the need to change it.
For example, I like a 0.3Ω build in my single 18650 mechs with kanthal coils. To get the same resistance at 500F with Ni200 coils, I do a 0.12Ω build (that's the resistance when it's cold of course).
How did I work that out you ask? Two methods:
1/ Maths:
Rcold = Rhot / [1 + α x (Thot - Tcold)]
α = temperature coefficient of resistance of nickel = 0.006
Thot = target temperature of the build when it's hot (in Celcius) = 260 (500F in Celsius)
Tcold = room temperature (in Celcius) = 20
So, for Rhot = 0.3Ω, that works out at Rcold = 0.12Ω
2/ Empirical:
Math is boring So what you can do is try builds in the 0.1Ω - 0.2Ω range when they're cold, screw the atomizer onto a regulated mod running the ArcticFox firmware configured to display live ohms.
Set the mod in TC mode, dial the temperature you want, fire the mod and read the resistance the build settles at when it reaches the temperature you dialed. If it looks right for use on your mech, simply screw the atomizer onto it and enjoy.
Simple as that. Try it out, you won't be disappointed. Ni200 builds really add to mechanical vaping.
EDIT: here's a video to show that it's not bullshit or dangerous or anything:
