Good: significant weight difference (easier to pull off the spool too)
-will not store (dangerous) tension in the cable
- higher breaking strength than steel usually at least 25 percent for similar steel
-wont rust, kink, or recoil.
-wont get wound up like cable when u take it off the spool
- will not "creep" (permanant stretch)
- possibly have a longer line if u use a smaller diameter line with the same breaking strength
-ummmm it floats?
- u can splice the line if it breaks
Bad: MUST use a hawse type fairlead (though that's probably more good)
- must use a rock rash guard
- more expensive
-abrasion from dirt and mud in line
-its slippery and can make it tangle on the spool. it can "cut" thru the winds on the spool
-heat can kill the line, watch spool/motor temps, most degrade around 150 degrees and melt at 300
hope that helps
