I didn't like the Nite cables, hope Hirsch isn't offended by that statement.
First, I don't think anybody has seen what's actually in the Nite cables. And I don't think anyone will spend $1200 to cut one open to find out. I think there are cables out there that are more proven than the Nites.
Second, the Nites are impossible to work with. Very difficult to bend, and if they're not bent perfectly (which can be extremely difficult to do) the cable will put strain on your connectors, which would lead me to believe that the mechanical connection is not perfect and I think this is something more important to consider than the actual insides of the cable.
Third, while I can hear the difference between a $3 RadioShack cable and a more expensive one, I honestly can't tell the difference between a $100-$200 cable and the Nites.
IMO, the best cable for me is one that has a proven reputation, is extremely flexible, has good shielding, and a good fitting connector.
My favorite cable from the meet was the Cardas Neutral Reference which I believe fits these requirements
