To date, every fish I have caught on my Tenkara rod has been on a non-Tenkara fly.

While I don't discount the effectiveness of any fly, it's all about what you feel will work for you and the way you fish. I know the trout well where I fish and I never planned to change the flies I used when I changed the way I presented them.

So far, trout have succumbed to soft hackle flies like a Snipe & Purple, Partridge & Peacock and a soft hackle version of the Gold Ribbed Hare's Ear. I also have done well with beadhead nymphs like the Prince and a flashback version of the GRHE.
