I went to a tenkara presentation featuring Daniel Galhardo a couple of months ago, and out of ~80-90 people in the audience, I was only one of four who had never fished before. The overwhelming impression I left with was that I would be at a distinct advantage over the folks who western fly-fish. They have so many habits to unlearn in order to adapt to tenkara. The questions asked by the audience focused on equipment, and disbelief that you could be effective with 'a rod, a line and one fly'. Daniel's message was that in keeping the equipment simple, it eliminates self-imposed variables that get in the way of learning technique. The initial learning curve is shallow, but there's plenty to keep anglers challenged - and rewarded - for years to come.
I bought the 12' Iwana starter kit. I'm impressed at the quality, but I haven't compared it side by side with any other brands. I like the TUSA rod warranty and return policy. They reduce and/or remove barriers to entry.
