My "bucket list" includes a number of pieces to be made of figured maple, and I have put aside a substantial quantity of stock as I find it is best bought when available, not when needed.
I have tended toward the most exotic figures, and I woule classify the variations in my stock as follows:
tiger maple - sort of more striped than plain, but not truly curly; sort of 1-D level of figure
Curly - most sought after figure for furniture, very attractive with waviness in 2-D
Quilt - a bubbly look, I call it 3-D figure; prized for guitars and other luthier applications. $100+ board foot price level
Burl - evenmore extreme than Quilt, structural properties seem compromised by discontinuities, almost crumbles
In my experience the hard maple tends to come from the Eastern part of the US, and the soft from the West coast,but not exclusively.
As pretty as the complex figures appear when stained, I am told they are a nightmare to smooth, some say that normal power tools cannot cope and they require extremely sharp cutters and even thickness sanding to finish without tearout.
