I've been dealing with a lot of flimsy, questionable cables in the past. Whether it's a guitar jack or a speaker cable, this is one of those pieces of gear that just needs to be right. There's nothing worse than suspecting one of your cables is responsible for weak spots in your sound. The pro snake is fat, sturdy, with connectors that feel like they can take a little bit of duress.
The the jack/speakon combination is awesome, as it gives you multiple connective options. Do recommend.
