Absolute top quality! 
 
Is this the best mainline Fluorocarbon for BFS and UL?  I think so
 
The  MAX  Fluorocarbon leader material consists of 100% pure fluorocarbon and has almost no stretch. It is particularly characterized by its extraordinary suppleness and enormous abrasion resistance.
 
Compare - hardly any other fluorocarbon on the market is as smooth as this! 
 
Further advantages of fluorocarbons are the excellent knot strength, the good tear resistance and the insensitivity to heat and cold. 
The material is almost invisible to fish underwater.
