I don't think there's a compelling reason not to use the Canare or Belden cable that BJC provides.
I wouldn't consider 15 ft a long run for a balanced, shielded cable at line level.
The natural alternative would be cables assembled to order from Mogami W2549 by someplace like ProAudioLA, who have given me great service in the past. (They do take returns, but with a small restocking charge.)
While you might hear very slight differences among those three options, difference are not likely to be musically significant.
Others will give you reasons to spend as much as a car on wires. Those reasons are mostly specious.
