I was a newbie not that long ago. I came here and asked alot of newbie questions. I think the difference may be as simple as the age of the newbie. I do not mean that in a bad way, it is just my opinion that with age comes the wisdom of life. I tried to phrase my questions in a way that would lead to discussions instead of yes/no answers. If Bob's question had been presnted something like this......
""Hey guys, I am trying to improve my climbing efficiency. I was wondering how small does the tree have to be for you guys to just say, I don't want the throwline, I will just scamper up it.""
Just my thoughts on maybe the reason the question got treated the way that it did.
