RE: .074 powered
Don't mean to change the subject CP, but what do you think of the Spectra "Spider Wire" lines now? They seem to have withstood a pretty hard jolt at the end of your lines, evidently hard enough to nearly rip the wings out of the fuselage!
I admit to winding them rapidly around the Sig or Blackhawk handls, and rubber banding them to the wings between trips to the field. We could never get away with that on steel lines.
