Bill,
Thanks for posting the link to BPL. I'm a life member and have been a member since 2005 when I found the site and became "enlightened". (pun intended) It's an excellent site with all types of backpackers from "normal" UL like me to the SUL extremists. But it's the SUL boys that pioneer the way to ever lighter gear.
I'm a regular contributor there and am know as a "Tarptent supporter". ;o)
When I moved to Nevada from Pennsylvania I had a Dana Designs 7 1/2 lb. Terraplane. Great pack but waaay too heavy. I now carry an Osprey EXOS 58 at 2+ lbs., my 3rd UL pack and the most comfortable.
I still have my Terraplane but it's only for winter backcountry use when I carry more bulky items and need its big volume.
John,
I suggest you join BPL (yearly or lifetime) for the good info on many topics from gear to routes to food & cooking. Or just lurk and read the posts. To read the full articles you need a membership.
