OK, did the multi reel build of the backing and line. I used some 3lb fireline crystal that I had on another reel as backing. Then a double uni that went together first try with no issues, other than cussing my eyesight. Then the entire 100m spool of the premium line. Casts very well in the backyard as compared to most everything else I have put together so far. Water test tomorrow. Thanks for all the input guys, relaxes the indecision knowing when you’re somewhat on a path that has been used before. I’ll post the results somewhere tomorrow unless the rain keeps me home.
