What's that ohm out to? I'm guessing your diameter is in the realm of 2.5mm-3mm. Even at 3mm, I gotta assume that it's well below .15! Dunno why you'd wanna run that low. I suppose you can on that IPV (the IPV3 to be exact, correct?) I just think it's excessive.
I suppose it all comes down to preference, but at full power, that's gotta be a scorching vape. Either that, or it's being under-powered to keep it manageable, in which case, there's probably a more energy-efficient way to get a similar vape. You don't need to build that low to use every bit of that 150w.
Other than that, everything looks good, though misaligned parallels bug me. After I get a pair of parallels squished and pretty much where I want them, I like to stick the bit I wrapped em on back through them and pull outwards to make em nice and flush before making the final adjustments, though I find it's not often nessesary if I use pliers to pull the slack out of each individual lead before I take them off of the bit and mount them. If one lead is slack when you mount them, then that slack will always have to go somewhere.
