I'm sorry I wasn't addressing you specifically Riggs. I was just throwing that 'knot decreases strength' out there to build on the idea that there are precautions we need to take to make sure everyone goes home. Don't use the same knot for every circumstance, don't use the same rope past its life, don't tie a knot without considering that it is designed be untied and needs the proper attention -especially if there is a life or lives depending on it.
This thread has strayed from the original subject, and I am partially to blame for that, but we needed a direction to go and we weren't getting very far at the start. I have appreciated all your responses and have taken a closer look at the bowline as I reflected on Richard's point. It has helped me to think about a knot before I use it - not that I am saying the bowlines application has changed for me, but that I shouldn't take any knot even the bowline for granted just because it is the bomb!
The bowline is one of, if not, THE greatest knot ever to tie its way into my heart. I pray to the bowline gods to keep me safe, and you should too.
Thanks for all the feedback. I think we're done.
