When looking for winch rope read the specs. Dyneema rope, which is what it is called, comes in different grades. The least expensive is called SK75, then there is SK78, and finally SK99Max. The 75 is your amazon, Harbor Freight stuff. It will work for most applications of basic needs, 78 is a better built rope with a little higher breaking strength and usually has a UV inhibitor applied to it during the manufacturing process. The 99Max is the strongest of the ropes and if you want the best and strongest that is what you want, it is also about twice the price. I use 78 on all my ATV and UTV winches. Most ATV-UTV winches come with 1/4" cable, when I replace with Dyneema I install 5/16" rope.
You can still get 50' on the drum easy enough. You can order bulk rope and install it yourself, putting the loop in the pulling end is not that difficult. Also get some soft shackles to attach to your rope when pulling, it will reduce the chance of damaging the rope. I can make trail repairs with a ball point pen if I need to. As far as fairleads go, you can use new steel rollers, or a smooth fairlead, or I have synthetic rope fairleads on my stuff that has hard rubber rollers on the fairlead. The object is not let the Fairlead get nicks in it that will damage the rope. As always these are just my humble opinions and YMMV.
Another advantage to rope is, if you by some chance break it during a pull it will not have any stored up energy in it, it will fall straight to the ground unlike cable which will hunt you down and try to kill you. Been there done that.
