Bravely done! ;-)

FWIW I use taste-odor as a proxy for potential contamination through leeching. If a container imparts, for example, a plasticy odor with time, I ditch it for something else. The early Camelbaks, for example, gave a lovely waterbed fragrance with enough contact time, while the current ones don't. Also, sometimes drink hoses do this while the container itself does not. This is why I prefer silicone hoses (which your Hiker has) for filters and reservoirs. The bit of water in the drink hose sits in the sun and can get quite warm, so I try to drain it between uses. (I don't think of it as a health issue so much as a "yuck" issue.)

Cheers,
