I use LIVEWIRE 20 ft cable for guitar and George L .155 for patches. I've never really had any problem with 20ft. as far as tonal degradation is concern. I need the 20 ft because I tend to move a lot up in the stage. Plus, LIVEWIRE has a LIFETIME WARRANTY! George Ls are really nice. Custom cut your size and easy to assemble. Clear sound, too. I don't really use much pedals (wah, chorus, delay) so cable length is not really a big deal for me.
