Nope, I don't use pre-made shot line. I make the shot line long enough so that I can move the shot/float around to fish the riffle water or the deep stuff. I use 8lb Drennan Super Specialist for shot line, it takes a beating and has no fraying issues when I'm constantly moving shot around on it.. I rarely if ever have shot on my leader, flouro doesn't stand up to well when you start moving shot up and down on it.. If I'm going to a big flow like the Geen, I'll obviously re-rig the night before, but it's the same principle.. I don't run light tippet either, 4-6lb Drennan Flouro or 5.6-6.6 Phantom.. It will consistently bust off before the shot or main line.
