Buying silver colored "duct tape" has been a very frustrating experience for me. I'm sure there's good stuff out there, but I've found only crappy "duct" tape equivalents where I live.

With gorilla tape I get the performance I want. It's really good stuff and I don't waste any more time buying and trying every "duct" tape available.

I do, however, buy and use the cheap crappy duct for light duty tasks. But you'll never find anything other than duct tape wrapped around my water bottle, my PSK, my skiing poles and other objects where I find it handy to have a few feet tucked away.
