Does sub ohming really matter?

Does it really matter on a high wattage regulated mod? If you are able to make a large surface area coil but still maintain low ohms that should be ideal right? Compared to large surface area with high resistance. I don't understand how people can say it doesn't matter on a regulated mod. Lower ohms means hotter faster right?

Sub ohming is for people who use mech mods to get the wattage they want so with a regulated mods you can do that above one ohm.

Rodeo is right. If you feel up to a big wall of text, here is one of the best explanations/discussions I've seen on the subject, http://www.e-cigarette-forum.com/fo...ughts-about-sub-ohm-latest-vv-vw-devices.html

And later in that thread you'll see where even this is may change in the near future (temperature control over resistance or power).

One caveat: Some of the big watt boxes require a sub-ohm build to reach max power due to voltage constraints.

Bang on observation. This is why the current gen boxes have dual 18660s - so they can step up voltage safely. This effectively eliminates the need for sub ohm entirely. With 14v of headroom, one need only build a 1.3ohm coil to hit 150w.

Another issue with some box mods like the rDNA if you run a 0.5 build which is the lowest build the dna 30 allows you have no choice but to run the box 25 watts or higher. If you do not you get that dumb blinking ohm warning telling you that you have to crank up the wattage. sub ohm on a VV/VW is rather mute I find because the hire ohms give you more room to move your wattage range around. But like others said for instance on the sigelei 100 watt if you want to hit 100 watts you need to run under 0.5 ohms I believe to even be able to hit that upper range because it is locked to 7.5 V or something like that max.

If using a VV/VW I find the sweet spot to be around 1.3 - 1.7 ohms on a build. 0.7 works really well if you do not mind staying 15w or higher. Tip on a VV/VW if you really want to get some vapor chucking going on use a single parallel coil using 28ga Kanthal A1. On my veritas with a vertical single parallel at 0.6 ohms at 30 watts the flavor just explodes as well as the clouds. Super efficient coil and the vape stays warm not scorching hot.
