I've never tried a Little 59, but I have tried Vintage Rails, Hot Rails, Cool Rails, Chopper and ProTrack in the neck slot and I thought the Dimarzio were far superior to the Dimarzios (and this is coming from someone who tends to prefer Duncan full-sized humbuckers to Dimarzios).

I think you mean the DiMarzios were far superior to the Seymour Duncans?
