I bought a pair of Oktava MK012's and didn't see that there was a bundle containing two of these cables for no additional cost - I contacted Thomann and they happily changed my order to include them (free of charge).
I'm very happy to have them as they are clearly of better quality than the stagg ones I've been using (which I only bought because they are only 3m long, and I didn't think I'd need anything longer...I was wrong). The connectors are very nice feeling, and the whole thing seems to be of better quality material than others I've used.
Sssnake and Pro Snake are a good choice in my opinion, as they seem to last well, despite being resonably inexpensive.
A small negative is the choice of colours, Pro Snake only seem to come in black - for the most part this doesn't matter, but you may need to label them (especially if you're using a stereo bar and can't see which cable is which from a distance).
A cable is a cable, they aren't going to sound any different to any other (unless one of them is broken), so it matters more about build quality and how long it will last - that being said, I'd have happily paid around £10 each for these, and the little velcro cable tidy is a really nice touch that makes it feel a little more professional.
