Andy,<br><br>ROFL - not true, but funny anyway.<br><br>I think the Camelbak Rim Runner looks pretty nifty, but I don't know anyone who owns that model. The other Camelbaks I've seen are well-liked by the owners. My boys all use Platypus units and like them very much, but they are not a pack-substitute - rolled up jacket is about all that can be added to the model they have.<br><br>Tom
