Since presumably the point of ultra light backpacking is comfort, any item that hinders that goal doesn't make sense. I have an ultra light pack (GoLite) which i don't use very much because I also have several which are more comfortable and balance better.
I think nearly all of us value lighter weight. I haven't met many ultraheavy backpackers lately. The trick is getting a reasonable balance between light weight, comfort, versatility, and safety. I am quite content with a heavier pack which carries better.
one or more gifts or other benefits from the co-op.
