I'd LIKE to say the weight wouldn't be an issue for me... but I already HAVE a chain, that would interface with both the security padlock I own AND my U-lock. It spends a lot of time on my rolling tool platform in my garage! 3' of chain weighs a LOT more than even 9' of 1/2" cable!

It might depend on where I wore the chain; around the waist, I'd feel the drag on my legs. Maybe over one shoulder, like a courier bag.....
