Wet fly fishing is really quite simple and if you like to look at the scenery it's the way to go as you can almost do it by feel.
Wet flies can be viewed by the fish as emergers, drifting nymphs, drowned flies, egg layers or even small minnows
Most people will fish two or more flies at a time and let the fish decide what they want. You can either match the hatch or prospect with attractors.
I usually go with something like a dark and a light fly or a peacock and a dubbed.
Depending on the current and depth, you want to cast across and quarter down or cast and quarter up. Mend to let the flies sink and then point the rod to follow the flies downstream. At this point, you can manipulate your flies in a number of ways. You can speed up the drift by mending down, or slow it down by mending up. You can pull the flies into a feeding lane or twitch the flies to animate them.
Using the Lesienring Lift
is a deadly tactic on a likely lie or a sighted fish.
When the flies finish their swing and are hanging below you you can still fish them out by stripping them in and let them fall back or just let them hang in the current.
Don't skimp on the tippet when fishing wets. The take is not gentle and will snap a light tippet. I use 3 or 4x
In fast water, most often you won't even have to set the hook, but when you do, use a "slip strike". To slip strike lift the rod tip while letting the line slip through your fingers. This is enough to set the hook while still protecting the tippet
