Why?
Jim:I am sure that they lighter line would do the job, but why? You could not possibly looking at the cost savings. These lines will last for 10-15 years if you use high quality line and keep it out of the weather as much as possible.One of major problems with thinner line is the effect it has on your hands with you are trying to lift a sail or sheeting in a sail. The thinner the line the more it 'cuts' into your hands. I would stick with the larger line if I were you. You can contact Hunter and ask them the recommended size of the lines for your specific model.
