It depends on the water that I'm fishing. If I'm fishing fast running, boulder strewn rivers I like a fixed rig. It sinks quicker, and doesn't hang up as often. I like to fish my reels in direct drive, therefore when I'm dropping line I have more contact with my weight. If I'm fishing my home river in the winter for frozen summerruns, the pools are generally slow and the bottoms very fine gravel I like a slider. The fish are very lethargic, and will often pick up a bait and swim away (before I ever feel the bite) therefore the slider allows some line to move before the fish figures out that something is "fishy" snit
