I use a 6' as well, unless I'm taking one somewhere that requires a shorter lead, like a dog friendly store or even the vet sometimes if it's a busy time. Then I use a short tab/traffic lead just to keep them close.
I only suggested the 4' to help with control until the pup learns to walk appropriately on lead. I never thought about putting a knot in it though. That's a great idea!
