Speaker cable length for L/R channels critical?

I have a good system that utilizes some older discontinued speaker cable that I like a lot. It is 10 feet in length and I need that length to reach the left speaker. The amp is not (and cannot be) located center between the speakers.
The problem is I wish to biwire and have an opportunity to buy a 6 foot pair. The question is this: Can I run both 10 foot cables to the left speaker and run the 6 foot pair to right without any wierd effects like "ghosting" or have one channel be clearer or louder than the other? Any ideas? Thanx

does this explain why, when I turn on my sub, the entire frequency range that the main speakers produce, top to bottom, sounds richer to me? I've wondered about this recently.
Thanks,

OK, so here is a question.

What is better? To have a 4 foot and 10 foot run? or to have two 10 foot runs where the excess cable will end up spooled on the floor?

I would definitely have the 2 10-foot runs.
At one time I had a similar unequal run of Cardas Cross to my Aerial 10ts & it always sounded funny & flat & I always had to move my chair around. I switched to equal lenghts of Cardas Golden Ref (still have them--great, smooth cable, even in extra-long lengths) & everything clicked into place. I would never have an asymetric set of any cables--just bad karma.

Slappy: Neither. It's a horse apiece, as they used to say.

All speaker cables have some flavor - complex reactance
Cables with less flavor will exhibit slight differences based upon the interactions with your specific components.
It's like comparing 10 licks of a chocolate ice cream bar to 6 licks. You are getting more "chocolate flavor" in the 10 ft set.

If you have well matched, very revealing high end components - I believe variations in speaker cable length should not exceed 25%. For most "good" systems - it will be hard to detect a difference.
