DIY ICs

I now have had a cabinet built for my components that is recessed into the wall. I can access them from a back room. My idea is to make my own ICs so that I can make them the exact length necessary. Some will be quite short, ranging from 1 foot to two meters. I want to know which is your favorite DIY IC raw cable and DIY RCA connectors. I will make custom lengths and can re-do and re-size if needed in the future but my idea is to keep them as short as possible. In the past I have preferred solid core pure copper coax type cable with silver solder, but I am open minded and will consider any and all types of cables and connectors. Thanks.
