The Big Singles are great, I love 'em, but I always recommend going with the Fat Stacks (or just one in your case...unless you're just dead set against it), because it gives you more tonal options. By installing a coil tap on the Fat Stack pickup, you effectively convert it into a Big Single, PLUS you still have the tone of the Fat Stack as well...two very different pickup tones with the flick of a switch or the pull of a pot.
