I've run many a synth line at about every angle you can run off the front and back of rigs through rollers and not once "pinched" a line. I've heard the term but I've never seen any situation that could be considered "pinching" a synthetic line if the rollers are actually rolling. You do have to maintain and occasionally replace rollers though I'm sure few do.
I think that is someones sales pitch myself.
I've run many ropes, line and cables across many pieces of hardware and there are instances where you want the friction to control the speed of the load but your gear wares out much faster. I have a break rack we use in training classes to show students what dirt in your line does to the solid aluminum rungs cut almost in half in the nice smooth diameter of a 1/2 inch line, the cuts were done with one long fall, and there eyes are as big as saucers every time. Fortunately the only load was gear.
If you choose a Hawse make sure you know how to inspect your line
every time you coil it back in. (edit) you should inspect you line regardless what fairlead you have.)
Don't let anyone step on the line - it drives dirt and rock into the core of the line and the dirt and rocks will cut through the line and usually when its under load.
Don't leave the line exposed to the sun and elements the UV treatment doesn't last forever.
You will need to replace you line every so often. They don't last forever. We replace all synthetic lines after 6 years, 3 shock loads, or sooner if an inspection shows damage to the core.
The point is there are pluses and minuses to all combinations of wire, poly, Hawse and roller. All I can do is give my opinion and the benefit of my training. It's up to you to decide how much you want to spend.
The argument about switching to a Hawse to get a couple inches just doesn't set right with me. There isn't any tech move that 2 inches is going to keep you from doing.

I've seen a number of winches sold with Hawse, no offense but that doesn't mean anything other then they are trying to sell you on an idea.
Y'all have brains - get the information and make your own educated choice.
