Kimber Kable 12TC vs. 8TC for 15ft runs.

12 tc is 8awg, and 8 tc is 9awg

I was considering going to a pair of 12TC, but went with a second run to have double 8TC biwiring.
The 12TC is a little heavier than the 8TC. but not much.
The claim is the 12TC has better bass.
With the 12TC internal biwire would allow 4 strand for mid highs and 8 strands for bass.
(or 5 and 7)
I already owned the old blue/black 8TC, so i added the white/clear for mid highs and used the blue black for bass.

Thanks all. I purchased a set of 12TC.
