Twine size,strength

Over the winter I have upgraded my baler from a 311 to a BC5070, I have always used the cheapest 9000 plastic twine in my 311 because that was the best luck I had, the stouter 170lb strength twine would never tie right wouldn’t cut it everytime, so I was wondering what y’all were running through yalls? I guess if everything is well it should handle the 9600-170lb fine right?
