Using low quality cable can seriously suck the life out of your sound. Even a little patch cable in between pedals can have an effect - I was amazed at the difference when I got my Spectraflex cables.
However, for my two patch cables (wah -> chorus -> flanger) I use Monster Rock 8" patch cables. Generally I don't like Monster (hype, price, reliability/durability) but for a fixed installation they're OK, the sound is good & 2 little patch cables didn't exactly break the bank.... :)
