So truth be told, shielding is shielding is shielding. I prefer to be overshielded than risk it. Also, I'm a stickler for how the shielding operation looks.

JCH...just shield the thing. your pickups are quiet. You should be more worried about ground-shorts! Oh and which wire to use. Go vintage. There's no tonal difference, vintage is just easier to work with! Peace. Love. And bobby Sherman!
