Define "shiny". Are we talking more a machined finish (e.g. McGizmos), or shiny as in polished shiny (e.g. titanium Quarks)? I'd vote for the former. Second place would be bead blasted, with polished shiny coming in last.
I did'nt correctly expressed myself but I meant the kind of brushed finish that TI will develop over time from being scratched and manipulated. About real patina (natural oxidation), I think that with time TI can get a blue shade but can't confirm...
Machined finished for me, but its for practical reasons. I love shiny, but if you actually use the flashlight it will scratch. I'm tired of repeatedly buffing items so they maintain their shiny look.
