Personally I love this tarred line (twisted) but you may like braided. Braided may have a different chart, so do check!
 | When Purchasing, double check line size to ensure that you are getting the correct size you want to work with. |
Can you please tell me what size twine I should be using for a three strand twisted 1/2″ anchor line?
Thank you
