The only other difference I noticed was pretty minor; the washers alongside the four outer blades seem to be slightly bigger and more of a bronze color.
I love matte black, but something about these scales looks cheap to me. Do they look different in person, like some cars look better in person?
Can the nameplate be popped off? If so you might be able to replace that panel with a blank one for engraving...if you know how to shape metal or know someone who does
In the pictures of the Charge Ti and AL side-by-side, the AL looks wider. Is it noticeable maybe due to the washers or is it just my eyesight?
