Over under, when done correctly, should have no kinks at all. It may depend on the type of cable you're using, I have no experience with silver cables. I've worked news audio and could take a 75 foot cable, hold one truck end and throw the cable out to a straight line and they uncoil perfectly and lay straight. But, these are just regular Belden xlr cables, although Mogami, Canare, and musiflux all perform the same way... Like I said, maybe it is the material the cable is made from... I only use regular cables, have for many successful years.
Best,
