Hawse fairleads are "standard" equipment with wire rope on most winches below 12,000 lbs. Roller fairleads are an option. The advantage of a roller is pulling from an angle. The greater the angle, the more the roller is a benefit. The main dis-advantages to a roller are the additional distance that they protrude from the face of the mount (as that may affect approach angle) and the fact that they should not be used with synthetic winch ropes.
as a general assumption, you are probably better off running a roller with a cable. I was. But you must also keep in mind that they are vulnurable as well. My roller fairlead got bent up and pinched the cable, and ruined my winch (it wasn't top quality but still... ) live and lear, huh? But really, it depends on what you want to run through it.
also depends how often you "plan" on using the winch. several times "every" weekend, a roller would be better for the cable. i have a hawse that was used WAY too much. however as much as i "plan" on *needing* a winch, i'll be just fine with a new(er) hawse fairlead.
