Bob, you can have your opinion, you're entitled. When you start throwing out profanity, you lose my attention and respect.
As for BobR, if you don't consider counting the number of sections of toilet paper (apparently 6 per day) obsession with weight, you don't know obsession...but of course, that was your description. I also consider Bob a friend, whose unending search for ultralightweight solutions I greatly admire.
Bob's title for his pack choices is titled "the Ultralight Pack"---I presume he knows how he wants to be described.
Do you really think he should shut up too, because of his style?
He enjoys discussing his choices and decisions with those interested, but that apparently would not include you.
By the way, the catchphrase of the Ultralight Community is "hike your own hike" HYOH, which means ----do what you prefer, I'm not going to tell you what I do and you MUST do.
