Heres a cheap cable damper.. Your bushshirt

and its multipurpose when its cold it keeps you warm, we all know pulling cable is hot work well what better than tieing your bushshirt to the cloths line you've just pulled out behind and when you winch in it comes back ready to put back on now you've cooled down again

don't know how legal it would be at winch comps but I've done it more than a few times
Normally I use a large piece of rag, all its there for is to create drag if it all goes wrong it don't have to look fancy
As for plasma, it is expensive! don't last as long, dosn't like friction or sunlight but....

its lighter and you can get more on the drum!
I'm old fashioned, for me (I'd use my winch 20-30 times a year) that dosn't add up to the extra cost and for mantinace of wire all you have to do is drip some diesel on the drum now and then!

no washing etc
oh and you can splice wire you can't do that with all the plasma ropes!
But if you want cheap plasma PM "Jungle" he's one of the guys on site he was doing a deal last year on the stuff and he knows all you need to know about it
