I agree with everyone above. Don't let other people tell you what the right weight is. If it is working for what you want to do then why change?

If you want to drop some pack weight (so you can go farther/faster/be less tired when you show up) we can help with that too. The cheapest way to drop pack weight is not put as much stuff into it. The "oh... I might want that"'s are the heaviest things.
