dalew,
I've tried the bigger looms but ended up with something like these:

The fancier looms always seemed to be too bulky to fit considering the inner fenders and headers etc.
Others also make some of the clips in different colors or with a chrome finish. I do like the plastic ones as they are more resistant to crossfire and are lighter so they don't stress the insulation of the plug wires.
Just my fiftieth of a buck!
