Another very good one:
WWW.COBRAWIRE.COM http://www.cobrawire.com/x-flex/x-flex.phpI dissassembled 50 Watts broken argon laser at work and found very flexivle wire made for 80-100A ( AWG 6) and got the part number wrote on it and found the supplier.
This wire ( the AWM 10070 or AWM 10069) compare easy with the turnigy ultra flexible wire but with higher inductrial grade The stranding o fthe 6 AWG is: 266 X 30
