What would you guys recommend for wire looms? I'm getting ready to do my exhaust and the wire looms that are on the motor right now are toast so i want to replace them while i have it all apart. (this is for my 63 pick-up with 327) I'm leary to purchase the aluminum looms with nylon clamps because that is what i have now and the nylon clamps have all broken from the heat (i belive they are cheapies the previous owner put on) however i've also read about spark crossover when running wires through an all metal loom (they look very nice but i'm not interested in detonation), that leaves the simpler style plastic seperators but those look cheap.

So......which style would you guys recommend? A specific brand? I don't mind spending the money to get a very high quality set as I would like it to last a long time, thanks for the opinions as usual.
