I buy the cheap ones. I like the 10" ones for most everything. I have a few smaller ones, some larger ones, some triple-tapers, and a banana for the once in a year or two when I need it, but it's the blue 10 inchers that get all the use. Sure they mushroom. Chop 'em back into shape, or rasp 'em if that's your flavor, whatever. Pitch 'em when they're done. Wedges are both necessary and expendable. Don't get hung up on this stuff.
