I have a Maple neck Strat, too (ash body though) and the Holy Diver neck sounds AWESOME split. Better than my Fender Texas specials or any other single coil I've played, really. I'd go as far and say that I would prefer the split HD over any "real" single coil.
I soldered a 500k resistance in so that effectively the pot value is reduced to 250k, that helps a lot, too!
