DIY balanced interconnects

Here are the instructions for proper connections of both RCA and XLR cables.

Kijanki: This simple low cost DIY cable kit has everything you mentioned. It's a great kit - highly recommended!

Thanks for the responses so far. Thanks to Danmyers for the post on construction (even tho I have no interest in Cardas). I note these instructions say to connect the shield to chassis ground on the source end only, as opposed to Kijanki who recommends the load end only. I still think connecting the chassis grounds to a common (preamp) end would have some merit (and a reason to DIY).
I see 2 votes for Oyaide and as I am intrigued by the possible benfit of single crtstal/OCC cables. The Vampire CCC-II is also a cast Cu cable at half the cost of the Oyaide. I am surprised Kijanki would not consider these to be quailty materials.
Of course the real reason for DIY is $$!
BTY the new cables would be compared to Kimber KCAG cables originally bought as RCA and coverted with Neutriks to balanced as i changed components. I have had these cables at least 12 years.
Also note that I tend to agree with Ralph Of Atmasphere and do not expect to find huge differences.

Oldears - I'm probably more lazy and making things doesn't thrill me as much as it used to. When I was about 16 years old I was building EL34 100W amps and really enjoyed it. Now I don't object anymore to prepacked goods - perhaps because I can afford it and maybe because I'm more lazy as well.

Kijanki-Maybe when you retire you will become intersted in DIY again! I started audio building Dynakits and have now gone full circle.

Oldears - It interested me before it became my profession. Now I'm left without a hobby (and time for it) but should be enjoying "project" when retired.

Technology goes toward SMT and often is very layout dependant. Building class D amp, for instance, would require extensive study of PCB layout. There would be always something, I guess, to put my hands on - maybe tube amps just for the fun.
