Just got a Mutation X in the mail, copper, planning on mating it up to a XXIX clone coming from FT, also copper. I'd like to do a .25-.3 ohm build on this guy. I have 24-28 awg kanthal available. Looks like I have to do duals so my thought of a short-ish twisted 24 awg single is out of the question. Dual parallel 26 ga maybe? Most of my builds are around .4 - .5 ohm, dual with 26 ga. Anyway, not in a huge hurry to build it. I'll be using authentic VTC4's and VTC5's, for what it's worth.
