I use a bowline everyday and it’s a great knot but if the knot was going back and forth between slack and tight I would use something else because it could work its way out.
Agreed. I've always been a big fan of the bowline but at some point I grudgingly accepted that sometimes there's a better knot. I didn't like using the figure 8 at first but quickly got used to it and it's a good choice for the OP.
