To this point I have only used the HSS lifelines. I always use them and will never sit in a tree without a safety line. After checking online, the HSS lifeline 3 pack is running from about $100 to $130. The Muddy lifeline 3 pack was only about $85. Is there a significant quality difference between these two products? Can anyone tell me about real world unfortunate accidents involving the Muddy lines that saved you? If I can save a dollar and keep the same level of safety I am all for it.
