I have all my reels spooled with either mono or fluoro backing, then filled with 30# braid (color not important), then 25-30 ft of 25lb fluoro tied with Albright specials or double unis. The fluoro is invisible to the fish.

I can run dipsys or cranks off of any rod without fear of breaking the line. Leaders from dipsys for spoons or shallow cranks are 6-7ft of 25lb fluoro.
