So years ago when I was winch shopping I was also shopping syn ropes so I could upgrade my spool during the order process.
What I learned was that MOST winch ropes look the same minus color differences as far as how they are woven and feel in your hands.
The kicker was the materials they are made from. So Dyneema is a patented material made from UHWMP or something. Lol
It comes in like 2 or 3 different ratings. SK65 and such.
Anyway the main differences between those and other winch lines is the cheap ones are made from Kevlar and other materials that yes are super strong but are not as resistant to UV light, bending and abrasion.
I don't run dyneema, but it sure looks like it. Lol
The off brand stuff works like a champ for us weekend warriors. Especially if your rig is stored inside.
It's the guys that log hundreds of hours in seat time with super rugged use where they see the difference between dyneema and the stuff we run.
I know, I only post up like I'm some kinda know it all. I don't mean to come off like that. I just do a crap load of research before I buy things. Just wanted to share with you
