I'm going to suggest Riff Raff humbuckers-plenty of bite to drive all that maple(which isn't as bright as everyone says!),.
Must admit i hadnt considered the Riff raffs but i am sure they would be a good choice. The guitar isnt that maple heavy though, well not in the traditional sense anyway!! Tims right though, I have done a couple of limba/maple guitars and they were all naturally nice and crunchy and very satisfying to play even unplugged.
although for all you tone cooks its best to think of the top wood on this as something denser than maple. Usually spalted maples tonal characteristics are non-existent and its just decorative because its so soft but in this case its been acrylized so is much harder and denser than even normal maple. And dont be put off by the 'acrylic' word - The wood gets fully impregnated all the way through with a special polymer of some kind - afterwards it has all the properties of wood with very few of its weaknesses.... but it still sounds like wood.
I have used the acrylised B/E maple for a fretless bass fingerboard and it sounds and feels like an ebony board but wears even better than that
