Every sigelei 100W+ has the disclaimer :
*100 Watts can only be reached on the Sigelei 100W if you build a 0.15 – 0.50 ohm coil. This is due to the 7 Volt limit on the device.*
So, ya ... not sure of your source, but I really trust the manufacturer
Actually, the Sigelei 100W+ can go up to 8.5 volts, the prerelease versions were capped at 7.0 volts but the production versions go up to 8.5 volts. There is still some confusion over this, with a lot of sites still showing the notice about the 7 volt limit from the preproduction models. At 7.0 volts you need a 0.49 ohm or lower coil for it to fire at 100 watts. 8.5 volts and you need a 0.72 ohm or lower coil. This is direct from the manufacturer -- because of some people saying it was limited to 7 volts, and others saying 8.5 volts, I emailed Sigelei a few months ago, and they confirmed that production models can output 8.5 volts.
But that doesn't matter with what I am talking about. You said earlier that you typically fire your 0.5 ohm coils at 25 watts. I went with 50 watts to explain what I meant, but at 25 watts it's even more dramatic. You can use a 2.9 ohm coil on your Sigelei and get 25 watts out of it before hitting the 8.5 volt limit. Even if you somehow got a preproduction model with the 7.0 volt limit, you can slap on a 2 ohm coil and still put 25 watts through it.
My point was that unless you want to go up to 100 watts you don't need to sub-ohm. You can use a higher resistance coil and still get put quite a bit of power through it -- which means you can use much thinner wire and have the coil heat up a lot faster, or you can use slightly thinner wire and have a lot more surface area against the wick (which will heat the juice more evenly). With a mechanical mod the only way to increase power is to decrease resistance, but with high-voltage VW mods like your Sigelei 100W Plus you have other options.
