I used a bully spider which is a sinking fly with lead wire in the body. Since the trout were feeding high in the water colum this fly should have sunk beneath the feeding zone but there was a pretty good breeze going on and the fish were downwind of my anchored kayak so I held the rod high so the wind could catch the line thus the fly stayed right where the trout wanted it.
I also should say that I was fishing small lake that was very heavily stocked with trout.

Deathb4disco,
You really need to try tenkara from a tube. It's a hoot!
