I run floro leaders (seaguar) for spring Browns. Or if I'm fishing the top 40 ft in clearer water. And on my junk lines. Down deep or in muddy water I don't. I was catching spring kings last month in 40 fow (brown to green tinted)...down 20 with straight 20 lbs big game. Last summer we were catching kings down 80+ on straight 30 lbs flea flicker. This was with spoons. I don't leader down when using attractors.
