It seems like there are a couple people around here that get just plain annoyed when they see my name!
Lots of times I'll have a question that's important and then I forget what it is. Or I want to do a search but then I forget what it was I was going to do a search for. Very annoying, yes.
Anyway, I did build some 40' star quad mic cables for myself, and have used them. They sound fine, I don't know how much of an improvement over regular mic cable they are though. I have so much gear that building star quad for the whole studio seemed really unattainable. I've built *hundreds* of cables as it is, and I'm a little tired of it at this point. So cable that's nice and easy to solder is tops with me!
There's also the size factor. Mic cable is pretty thick, and if you have a lot of cables going in and out of patchbays it really gets crowded. That's why I'm a big fan of console cable.
Another brand of cable I love is Connectronics. It has a conductive plastic shield instead of a braided metal shield, so it is extremely flexible. It's as easy to cut and solder as cable with foil shield, too. I use that for certain connections, and for my front of the patchbay patch cables. The Connectronics cable is the kind that feels sexy. I know that sounds sick, but I think pretty much any engineer knows what I mean.
