Some serious misconceptions here. The only thing the Hawse buys you is clearance.

Any friction you can take out of a haul system the less ware and tare on the equipment and more power you can put to the load. Rolling friction is much less then sliding

Metal to poly will create ware and friction. If you create enough friction you can and will melt your synthetic line. Remember the heat is being stored up in the fairlead and when you stop you are concentrating all that stored up heat on the same spot on the line.

Now granted you aren't going to generate the fpm that a climber or technical rescue system will create (person falling on a rope) but you will create much more friction rubbing then rolling - simple physics. The more friction the quicker you ware out the line.

Wire (steel) rope on a steel Hawse will still ware out and create burs and snags in your cable. Wire on aluminum gets you more burs or galling and the added bonus of dissimilar metal corrosion in the cable (how many of you actually clean off your cable - be honest).
