Good idea for the shrink tubing, I may have to try that. I just got my first Arc AAA last week, and after trying it out it immediately replaced my Mag Solitaire as my keychain light. My black Solitaire I had on my key ring for several years was mostly silver from several years of use. Then again, maybe I'll just leave it "unwrapped" since the wear seems to give it a bit of character.
