A reasonable answer that we may put to the test sometime soon. I'd like to try Sweet Spot Reveals with high quality materials and I'm checking out some candidates now. Thanks for posting what Josh says, but what do you think about the original question yourself Agisthos?
I think it is the logical solution. If I was making my own cables, I would keep the conductor the same for consitancy, then by trial and error try different types of geometry until I hit on what worked best. (with a cable cooker to burn in each design of course)
