Great Info !
About the L-com cables...
When they say ultra flexible, does that mean that they are ultra durable, to withstand many repeated movements, - OR - do they offer ultra low physical resistance to movement (like the ZWO USB3 flat cables that they use wth their cameras), OR BOTH ?
So far, the ZWO flat cables seem to have very low resistance to movement, but only in the flat side orientation, of course.
I too am looking for some versatile USB3 cables that are reasonably durable, but with extremely low physical resistance to movement.
