Exactly! It's not a tool for big fish, it might have been in the interview on the Orvis podcast that Daniel Galhardo talks about these limitations with Tom Rosenbauer. If you're targeting big fish or there's a good chance you'll hook one it might not be the right rod to be using. That said, here's a video of Daniel catching a nice brown. Personally I'm hitting small streams with fish smaller fish.
One nice thing about Tenkara is that if you break a section you might be able order a replacement, I know Tenkara USA does it. I've never done it, but if you unscrew the butt cap the sections will come out the bottom and you replace the broken one. Still better not to break them, but a nice feature.
