After giving it some thought I was thinking the same thing about the pos/neg length differences and how they would affect the sign wave timing . Also after pricing out the wire I would want it became to expensive to consider trying as an experiment that may or may not work .
But reading about that cable design I discovered the Iconoclast cables designed by Galen Gareis a former Belden cable engineer , these cannot be DIY'ed . they have a similar design to the Alpha Goertz in that the positive and negative are laying flat one on top of the other . Not cheap but at under $1090 for 6 ft within reach .
