id shed weary on the cadence. i know they used to not specify that any of that Copper lines were actually pure OFC. additionally i believe they stacked up poorly in the great 0 gauge comparsion thread. I have used KNU, the monster wire listed in this thread cannot be beats for quality and price, 30 ft for like 70 bucks? a steal. and Streetwirez. Knu was by far the most flexible. The monster cable has a tiny plastic inner rod. it makes it be a little difficult to bend when its cold out. otherwise its beefy wire. hope you find what you want!
