I did notice the weight difference compared to alu version, but I don't mind since copper is supposed to be anti-bacterial. Noticed that the orange aux lights are dimmer than the red aux ones, which is good.

Glad to see the switch looks like it's also made of copper. For now I prefer it to be clip-free, and just pocket it.

I understand why people are requesting a Titanium version of the TS10. Not really a fan of Ti though, unless it's for my bicycle.
