    I've now had five months experience with the ProtoWizard orange wax
    and, bar none, it is the finest available. It burns out as nicely as
    the Ferris/Matt green, purple, blue or any regular injection wax and
    at the same temperature/kiln cycles. It carves and machines far
    better than Ferris/Matt and there is no distortion of the shape as
    areas thin; there are no bubbles inside the block/rod (big problem
    with Wolfe wax and, to a lesser extent, with Ferris); ProtoWizard wax
    is less brittle than the green waxes so breakage is actually a thing
    of the past; and finally, of huge importance to me, you can see what
    you're doing. The green, blue, and purple waxes are so dark in value
    I've always had a hard time really seeing what I'm doing. It also
    seems to be less offputting to customers than the green. It's not
    exactly "metal gold" but more natural (and easier to see, did I
    mention that) than the Ferris/Matt products. 

    And no, I don't have any financial interests or kickback
    arrangements with the makers of ProtoWizard software and waxes.
