Speaking as the newest guy I've seen here so far, I think this type of "head to head' would be excellent.
If I were to set it up (you listening Caswell?

) I would compare the following:
- Polished Aluminum (naked, waxed or zooped)
Polished Aluminum with Clear Powder
Chromed Aluminum
... and just to spice it up a chrome powder with clear
Comparing those different methods always seems more fact than fiction to my not-in-the-business-ears.
If I had a website that sold gear for each of those options I'd be interested in a true depiction of the differences.
