Good Success with Keiryu
I've had good results fishing a keiryu-like technique. I use my Tenkara rod and a fly tied small (#16) on a #14 barbed dry fly standard hook. This leaves a small amount of space to thread on a live nymph or sow bug below your fly.
Flip a rock over and catch a critter(s). I like to add to my sparse arsenal (rod, line, forcep / scissor combo, small home-made Altoid fly box, tennis shoes) a small aquarium net.
Use a gentle cast or just drift it downstream. If the critter flings off you still have a fly. Usually you get a strike every cast.
I carry two fly patterns a Killer Bug and a Sow Bug.
Had a great day on the river last weekend (catch'em every cast) but I got some weird looks. Finally a well equiped dude with a particularly disapproving frown asked what I was using. I gave him a Killer Bug. He took the fly but couldn't hide his disgust when he saw my home-made Altoid fly box and my wet tennis shoes.
Said he hadn't caught anything all day...

As age slows my pace, I will become more like the heron.
The hooks are sharp.
The coffee's hot.
The fish are slippery when wet.
