The SC cord is intended to be used with a bracket. It was never intended for taking the flash off-camera on say a light stand without precautions.
I recommend NOT using TTL-BL mode with an SC cord. TTL-BL mode adds fill to a properly exposed ambient image, and it depends on many things to function properly. One is that it uses the distance as reported by the lens to set the power. This means that the flash must always be positioned so that it is the same distance to the subject as the camera.
Of course, TTL-BL should only be used when in bright ambient light, and with the camera meter zeroed, but that is true whether in the hot shoe or on an SC cord.
Regular TTL mode works exactly like when the flash is mounted in the hot shoe, and that is the mode I recommend when using an SC cord.

Be careful with the term 'CLS'. CLS does NOT mean wireless. Nikon Wireless is AWL (Advanced Wireless Lighting), and it is a subset of CLS. In fact, some CLS flashes, like the SB-400, do not work wirelessly.
>Did I mention the elimination of annoying pre-flashes?
There is still a preflash with an SC cord. It is called the Monitor Preflash, and that is used to set its power. In fact, this monitor preflash is the hallmark functioning of CLS.
