Jack Hise equipped me with a fluorocarbon leader back in October when I was privileged to visit with him. I struggled with clearing the water with it on my 4 wt. and have since moved it to a 6 wt. I am hoping it will help me find some of the larger browns that are being found in the Hooch now days. I had a friend from NGTO tell the site he and his wife saw a hawg of a brown in the area I haunt.
