@Lynn: "I know this is BPL, but...to spend that much money to save maybe 4oz on your total pack weight is not really the best idea. ..."
I don't know. Depends on how much money you have and where you find your happiness! I just replaced pretty much my entire kit from last year with new stuff from BPL, Nunatak, MLD, ULA, Trail Designs, Gossamer Gear, Tarptent and Hilleberg (well, I will have when it all actually arrives!). The stuff I have is quite functional (though I am saving quite a bit more than 4 oz overall, but spending more than a few hundred doing so!), but I get much joy in getting new gear. I'm like a kid in a candy store who just bought pockets full of candy, and I'm on a sugar high that can't be beat! Backpacking and cycling are my vices -- don't need big TVs or big new cars or big oversized houses, and I have no kids to send to college, so I happily support my vices with a big smile. And since the gear lasts much, much longer than a few dozen candy bars, that sugar high never really goes away! It comes back full force every time I hit the trail. And my used gear goes to someone else who will smile and continue to use it as intended. And I support (and in my very small way) help sustain the wonderful folks (Henry, Tom, Ron, Grant, Rand, Brian et. al) and their small homegrown businesses who continue to make high quality, lightweight gear (and they do it, I like to believe [since I don't know them personally], primarily out of a love for it, not simply out of a desire for profit). Smiles all around. :-)
