The other tip I would pass along is, in buying wood props, look for close grain running through the prop from front to back, not from LE to TE. There is a certain appeal in the appearance of grain running with the flat dimension of the prop; the visible contour lines of the grain are reminiscent of the old laminated props, which are pleasing to contemplate. But for better strength, look at the end of the blade for lines running the short way, the closer the better.
