Well, as it just so happens, I just made a twisted build for my Velocity (it's a Tobeco clone, can't afford Insignia's prices). Twisted 24 AGW Nichrome 80 with a 3mm ID, 6 wraps. Comes out right at 0.203 Ohms. I wanted to put it on my mech box, but the ohms were a too high. I was aiming for 0.1. I need a better ruler to use Steam Engine's twist pitch feature. Still, it vapes wonderfully on my Sigelei 150 watt at 90 watts. Goes through juice like a fiend though. Good thing White Label exists.
I think this is the only atty I could fit this build in. My El Cabron is technically larger, but the center post means I have to have the coils further from the center meaning that they would probably short on the topcap. Pics below:
As Grimmgreen would say, vapors are happening.
