Bi-wirring long run rear surrounds

I recently purchased canare quad 4S11 speaker wire to biwire my (B&W 805's)surround speakers. The runs are long, 35 feet and 40 feet. I was told at a high end audio store that biwirring long lengths wasn't a good idea. It would be better to use two cables per speaker post or doubling up. Any one have opinions on this, I don't know which way to go.

Lej, just what is 'the cardinal sin'?

Gas, I THINK your store was addressing possible problems (eg less-well-damped bass) from the increase in cable resistance that results from single-biwiring, ie biwiring with parts of a single cable. Long lengths are already 'too long', and splitting the spectrum by single-biwiring increases each half's resistance.

I stumbled into some AudioQuest double-quad cable (part of their flat-rock series) that was really inexpensive and I'm double-biwiring my 32- and 36-foot lengths with it.
