I would argue that you should not use canned air on lens elements regularly. In my experience it eventually leaves build up of the propellant on the lens, which requires deep cleaning from time to time. I prefer a manual blower.
It works significantly better if you place the fishing line over the back element of the lens, not the front. Obviously though, you have to make sure it is very securely attached.
