You guys are confusing issues here. The silver clad mil spec wire is perfectly fine for our applications, as demonstrated most notably by the Audio Magic Hyper Conductors line of cables. This is the basis of design for all the silver clad copper cables found on TS.com. Of these the BBee, Hydra, Dogstar, Busilver, Hi Ho Silver lines, there are hundreds of users that have been using this material for 3 to 4 years without issue. This demonstrates it's success rate. Granted, there are users that abuse their cables and have issues.
The teflon jacket is not rigid. It flexes and gives a needed. However, the tape wrapped vs extruded teflon is thinner and more susceptible to penetration; thus, one reason for techflex. The tape type is several layers thick and not delicate by any means, but can be cut or nicked, which will expose the shield. The techflex aids in prevention.
From my experience with this material, it sounds like your problems with the material stem from inadequate strain relief at the connector since your issues are isolated to the teflon at the connector or the wire breaking at the solder joint. The diameter of this cable combined with the fact that teflon is extremely slick make the strain relief even more important than traditional canare type cable. Without this protection the stress is transfered to the solder joint as the cable is pulled or as the cable rotates/twists inside the connector.
Not knocking any T's, just trying to share my experiences so folks aren't confused.
