HHAHAHAHHAHA, I don't know whether that is good or bad
Anyway, I was over at Digikey and noticed they carry an 80 conductor ribbon cable, ~$150 FOR 100 feet. It's 30 AWG, so 40 and 40 each in parallel will work out to 16 AWG equivalent. Oddly enough, the 50 conductor 28 AWG, when paralleled at 25 and 25 works out to somewhere in between 14 and 15 AWG.....
