PP twine ruins the fleeces on sheep wool too.

Back when I ran squares (my 575 has not left the barn in 4 years now, should probably sell it but when I do, luck will be I need it...) I always ran poly. reason being is I sold squares to horsey people and if they stored the bales, their mice would chew the strings. My 575 will run either. The twine discs are sisal / poly compatible.
On an older baler, you will have to change the twine discs to run poly because it's more slippery and the disc had to grip the poly tighter than the sisal. Probably need to change the initial tension at the twine box as well. Your baler manual will tell you what the proper tension is. I use a trigger pull gauge (firearms) to determine the correct tension. Trigger pull gauges are in ounces and pounds of pull and your manual will call out the correct value.
There is only one part number for twine discs on each model of NH small square balers. There are different billhooks for the twine types. Billhooks for plastic twine work just fine on sisal twine. 500 series and newer balers came standard with hooks for plastic twine.
