Shorter Drifts - More Fish. It may be a bit counterintuitive. You so often read about the wonderful long drifts you can get with a tenkara rod. I am convinced you would be better off concentrating on short drifts instead. This is definitely true with respect to fishing nymphs and I believe its true with respect to wets as well.
I've written about this before (probably several times) and will probably write about it again. I have been fishing with a tenkara rod (or equivalent) for over ten years now. A very large percentage of my catches have been as I was picking up the fly to make another cast. On the day that prompted this essay, a solid two thirds of my fish came as I was picking up for the next cast.
On some days, nearly all the fish I catch are just THERE when I pick up for a new cast. (As an aside, when that happens, you do not need an aggressive hook set.) Because I fan the area with casts, take a step or two and fan again, every fish that takes my fly at the end of the drift has had at least one if not two drifts past his location already. (If I was fishing 20' drifts, he might have had seven or eight drifts right past his nose.) Why did he choose to hit only as I was picking up for the next cast?
I think it's because as you pick up for the next cast the fly looks like an ascending nymph. It's the same principle behind the Leisenring Lift or the Kite "Induced Take." Unless you are extremely quick in picking up to start the back cast, a nearby fish can grab the fly before it reaches the surface (so concentrate on a slower, deliberate pick up). Although much is made in tenkara circles of pulsing the fly, a fly ascending to the surface is a much more natural motion than a rhythmic pulsing!
Getting back to the idea of short drifts, if your average drift lasts four seconds, (which is about what it should) over the course of a day you pick up for a new cast twice as many times as you would if your average drift lasts eight seconds and three times as many times as you would with extended 12 second drifts. I believe a similar strategy (and for similar reasons) is one of the factors behind the extreme success of French Nymphing. Shorter drifts = more pick ups for back casts = more Leisenring Lifts = more strikes. Simple as that.
