The dielectric is usually a concern when factoring in the capacitance of a cable. This requires two conductors carrying different voltages and a high impedance signal at a close proximity.
If you're air-wiring a wire, this is usually not a concern...
I also remember reading a article that interviewed several well-known cable manufacturers about cable burn-in, and many of them noted that the wire dielectrics, being physical not only absorbs energy, but re-radiates it.
They also referred to the concept of piezoelectricity.
Although I personally don't believe cables make a difference in audio, I have built several cables anyways for the sake of having nice cables, and when I do, I apply the best of my knowledge into building an ideal cable as long as the concept/theory does not sacrifice practicality and cost.
The impedance after a pot is quite high, adhesive heatshrink is pretty thick and the pot pins are pretty close together. Regardless, a inch or so definitely won't matter but then again, solder joints are pretty strong and the mechanical strength inside a case is
just as unimportant as the theoretical increase in capacitance due to the heatshrink.
I wouldn't bother worrying about it.. use whatever you have. It looks cleaner when the pins are heatshrinked over imo.
