That looks neat jason. I wanna know how it works out. It is certainly light enough. My concern using it would be that since it looks like it's a replacement bite valve, how's the flow through it, and
can I get water out of it without sucking. Basically I have three modes of water use:

1) sucking through the bite valve (ok this works)
2) dumping out water to boil (no problem, I don't even care about treating this..)
3) pouring out water into something that I'm *not* going to boil, but drink.

It's option 3 that I'm worried about being a problem with this critter. but please let us all know!
