Thanks Chris,

I'm going to do my best to test them both under real world conditions. Nothing that they wouldn't undergo in realistic wilderness survival situations: water, dirt, being dropped, stepped on, dropped etc.

I'm trying to borrow a digital camera from a friend at work to document the testing, but not sure i'll get photos unless I take 35mm photos from my own camera. Either way, I'll document the testing as best I can.

Matt
