Most of the time I run a slider with a longer than average leader (4-6'). With the slider you can still feel the fish take with the longer leader. Longer leaders allow your presentation to move around rocks where the fish are laying, plus the fish can see up, not down. I also believe the longer leader allows the presentation to waft and wobble more, attracting the fishes attention.

I only use a fixed when I'm throwing eggs which tend to get caught in the wind, making the slider run way up your main line. Also use a fixed when I'm free spooling, doesn't get snagged up as easily. Tight Lines
