rosewood=smoothness
maple=more snap
If the above is true, and it seems to be the consensus, than that explains why I like rosewood better - I am always trying to find ways to round of the shrillness of the high end - I like a smooth and probably somewhat darker high end - I have always migrated to a rosewood fingerboard, my personal fav - that being said, I do have a USA Schecter Tele with a very flat maple fingerboard that I love.
