I'm the odd ball of the bunch, but this works for me.
I've focus on any area deeper than surrounding water with cover. I've found a lot of dead four foot water, but have caught quite a few in 15 inches of water next to a root ball. What makes me a little different is I use a short four or five foot indicator leader from KSBASS here on the forum with color in the butt and a medium leader. I also only use one fly. My thought process is one... a short leader allows me to get fly line out of the rod for better casting. Two, most of my casts are close in because the fish are not as spooky. Three, if I get snagged, I pull in the line in to the tip and shake the fly lose. If you snap the line these small holes, they are toast anyway, so I get my fly and move on. Now if you get to the handful of picture perfect runs, you can switch out your rig if you like. I don't. I just use smaller drifts. Final note, dries always seem to work better for me in the riffles.
Tight Lines,
