Likely no one here has tried them yet. They sound interesting, but I figure that the Caddis Fly rods from Fountainhead are good enough for me and cheaper.
Just some of my experiences as food for thought. They may or may not be relevant.
FWIW, I am finding that for me:
1. After dabbling with both, while the Tenkara is fun I like a regular fly rod better.
2. I don't feel the need to spend a lot of money on higher end gear to catch trout and have fun. I caught scores of trout on the JMT hike with an $80 or so outfit and did not feel that the outfit limited my enjoyment of the trip.
I planned to use my Fountainhead Tenkara rod on the JMT last year, but on the drive out from the east coast bought an inexpensive 4 wt regular fly rod (Wind River Combo) from Cabelas on sale and on a whim. I took it on my hike, again on a whim, and found that for me it was more fun. I was still able to keep my base pack weight below 15 pounds despite having the fly rod, associated stuff, required bear canister, and quite a few extra items along.
