Canare L-2B2AT
Good choices, about half the size of regular mic cable, nice and flexible, especially the Canare. I used to heat-shrink the cables together before closing up the connector.
I mostly buy cables now, though I have made a bunch. I pretty much stopped making cables when I "went pro" and started making my living doing sound. It just became not worth my time.
If you decide to buy, I would consider EWI as a decent budget solution, and I would really like to try some of this guy's cables. Top-notch connectors and cable, very reasonable prices. You almost couldn't buy the parts for what he charges.
Bayou cables
ps-
I don't like having two cables where there could be one. When I buy pre-made ones more than a few feet long, I either tape them together every foot or so, or take off the TRS connector and use pieces of heat shrink every foot or so, and leave enough for a good fan-out at the TS end.
When I made them, I used heat-shrink, or one of two methods. I used the zip-cord like Hosa does, and a piece of heat-shrink to keep it from splitting past where I wanted. I think I just used bulk unbalanced RCA-type cable. I don't remember, it's been awhile, and I stumbled on a different method that I used because I had some extra mic cable and I just though it looked more pro.
I wired one end TRS, and at the TS end made a short jumper of L-2B2AT or similar. This jumper was wired as my return, and comes out of the back of the send TS jack. The TS return jack is then soldered to the jumper. So there is only one cable except for very close to your send/return jacks in your rack. Not worth it for short runs, but for six feet or more, it really cleans up your wire mess.
I also used this method when I made my insert snakes. Pre-made ones usually use twice the amount of channels as there are inserts, ie an eight-channel insert snake uses 16-channel snake cable. My 8-channel insert snakes use 8-channel snake cable.
