I got a set of strings and cables a week or two ago and I am very happy with them.
I had issues with my old (factory) cables serving started separating near the cams after 50 or so shots and just got progressively looser I was always having to slide it back to fill gaps in. I also had issues with the strings and cables being to thick so cables rubbing where they cross and the thick string and cables where most likely slowing the bow down.
I put Marty's string and cable on. I have at a guess 200 shots in them and serving is tight as can be and doesn't look like it will move at all ever. As I expected the bow was faster as arrows where shooting high and needed a reasonable amount of adjustment down to zero again.
