i believe maple is a faster fretboard, cause its smoother, but it wont make you noticible better. I have two rosewoods necks, and i must bring up this point, the rosewood on my fender is great but the rosewood on my epiphone les paul is kinda like plasticky, whats up with that, any info? o i also read in a report that rosewood creates more sustain then maple, however, i couldnt be exact as to how much more.
