B&D Crusher

Hello, new to the forum, I am going to be re conditioning my swathers this off season, we run New Holland Rotarys, all have rubber chevron rollers, they usually dry the hay down to were we are raking in 3 to 5 days depending on time of year, are the B&D rollers better? And if so why, I understand the full contact rolls can make the hay softer which has my interest, do they have replaceable stub shafts? Is there any other reason they are better?
