AW owns the 18350 universe. I have 8 of them and have sent 3 Efest '350s to the great battery disposal in the sky over the span of time I've been using them.
AW '350s are rated at 6.8 amps continuous, so I wouldn't recommend building lower than .8 ohms. Technically you could do .7, but you're going to murder those batteries at low resistances. If you build lower than .8, be VERY careful and monitor the heat buildup closely. Again, I would NOT recommend it. My '350 builds are around 1.2 - 1.5.
