The western USA maple tends to be redish and a good bit lighter weight than the Eastern hard rock maple. The grain seems to be more open on the Western maple and it often does not turn as smooth. Because of the softer more open grain it fuzzes up more than the Eastern hard maple. Those are the Western Maple's weak points when it comes to using it for structural parts, but for looks, the curl can run really nice and is about as pretty of a curl as you can find. So for points and butt sleeves the really nice Western curl would be hard to beat. If you were to have it impregnated and stabilized with color added it would make one of the prettier curl woods to core for cues.
