There might be practical differences for the infrequent cable builder among=
 different star
quad variants. We have used a lot of Canare L-4ES and left it out of doors =
literally for
years in monitoring ultrasound. It is inexpensive per meter, has good UV re=
sistance and
coils easily at low temperature. It has a braided sheath which seems much e=
asier to solder
to than some other higher end cables (e.g, Gotham star quad has a wound dou=
ble helix
shield). One aspect of some  cables is that they describe using cotton fill=
er to reduce
microphonics. If you nick the jacket (or it acquires non-obvious rodent bit=
es) the cotton
tends to wick and hold moisture, so there is  potential for long term degra=
dation that
might not occur in studio settings
