Hey JK. I use powerpro exclusively with mono or fluorocarbon leaders. I simply tie to a swivel with the powerpro and then a leader to the other end of the swivel. NO need to use more than 4 feet of leader (some may argue this). The truth is I probably use shorter leaders than most. I have methods to my madness though. Truthfully though, I never use 4 foot leaders, 3 feet is my very maximum length.
