Silver ones are equally shiny (ok ok, not as shiny as gold)... after all DYKWIA?

Mine are on my main rucksack using the simple loops (loops at both ends). With the "rope" version as opposed to plastic, they do don't protrude as much as a LowePro/KLM tags do (although the KLM promo was very good for custom labels IMO... now run it again! ).

And besides which, where are all your flyertalk.com luggage tags!?!?
