I would change "purplewood" to "purpleheart", the name it is most commonly known by. I would also move purpleheart into the common woods category as it is used all the time internally (coring) as well as externally in the butt and even somewhat common for shafts too. And while tulipwood isn't super uncommon, I wouldn't exactly call it common and it is certainly out of place in your common list. And many of the woods in the "fancy" category aren't exactly fancy either, just less commonly used that the main staples. Not only is ash not uncommon, but it is the most common wood used in snooker cues, but if you are only talking about pool cues then it is pretty uncommon (but not at all fancy). Several other things could be mentioned as well.
Without giving this much thought, if categorizing the woods somehow is important to you, the categories should probably be something more along the lines of:
Common coring woods
Common shaft woods
Common handle woods
Common forearm/butt sleeve woods
Common inlay woods
Less commonly used forearm woods
Less commonly used inlay woods
And if you are stuck on using "fancy" woods categories for some reason, you could add an additional fancy woods category for shaft, forearm, and inlays but "fancy" sure is awfully subjective.
