I have a ton of good quality RCAs. anything from 3', 10', 17' in 2 channel, 4 channel and 6 channel. All of em are tsunami, the middle grade ones. I also have a set of the really good 2 channel ones that retail for like 90 bucks.
The top link is the really good ones 2nd is the middle line ones. I also have a LOT of the older style RCAs, the middle of the line ones. They are excellent cables, i prefer the older style ones to the newer ones actually. I can get you pics of all of these if your interested, just pm me. Thanks
edit:you could even save yourself some trouble and replace the 3 sets of 17 footers, and just use a 6 channel. Its up to you, just let me know what your looking for.
