3401, the "Beast", is a legendary workhorse that can push backing plates to there limit if you do not lean to use light hands. Let the Beast eat, no need to force feed creating undo backing plate and foam pad heat. These Flex backing plates are very well made but remember they are considered consumables, pricy consumables. A little TLC, heat management, proper storage and maintenance they can last many years.
