Really professional grade? Berkley braided line review

What is professional grade anyway? Is everything else amateur grade?? All kiding aside were taking a closer look at this new offering from Berkley. With so many lines on the market is there really any difference or advantage or is this just new packaging for a new year? In this video well examine this line from a tabletop perspective, then (and more importantly) I put this line through the paces for 10 weeks.
