Bill, I have not tried the Cortland line. I assume you are referring to the Patagonia Tenkara kit. Yvon Chouinard's style of tenkara fishing just doesn't appeal to me. I'm mostly a fluorocarbon level line guy.

However, from time to time I like to experiment with other kinds of lines, just to try them out for myself, find out how I like them from personal experience rather than taking some one else's view as gospel, and expand my skills. So I have made lines from from western type shooting line. And used them with TUSA Ito, Ayu and Iwana rods. I've not tried them with the Rhodo, and I do not own a Sato rod.

While using that type of line is not my cup of tea there are several people who prefer similar lines, and several companies that make similar lines aimed at Tenkara.

Kazuya Shimoda - prefers a 3.9m 7:3 rod with .031 inch dia SL, shooting line. He likes it because it is durable and cast well in the wind.

The late Keigu Horie, who is called the pioneer of modern tenkara, preferred western fly fishing line.

I have made lines to the design at the following link - created by Sebata Yuzo in 2006. He recommended this line for people who lack the skill to make their own furled lines. He recommends 30# shooting line for beginners, and the lighter 20# shooting line for people with more casting skill.

btw, 20# shooting lines are generally about .031 inches in diameter, the same size line preferred by Shimoda. The webpage is in Japanese, but basically the yellow line is 4meters in length to which he adds a .5m length of #4 fluorocarbon level line at the tippet end. He used the Deep One, #6 (6号) salt water line to make the loop that attaches to the Lillian at the rod tip end of the line.

I've played around with variations of this basic design, to make different lengths of lines. And even substituted braided saltwater lines for the shooting line. And used Cortland or other brands of shooting line. Such as

Alternative similar lines would be the Badger lines,

Or the various Rigs lines.

I've not used the Badger or Rigs lines. Only my own home made lines made from western fly fishing shooting lines.

Anyway, the point is, a lot of people use versions of the Patagonia Cortland line set up with a variety of rod brands. I see no reason why it wouldn't work fine with the TUSA rods, but maybe the Sato wouldn't work well at longer lengths of line. Those kinds of lines may work better with a stiffer rod. The TFO rod reviews I have read called them a stiff rod, Shimoda uses a 7:3 rod, which is more a tip flex rod, but whether it is a stiff or soft 7:3 rod I do not know. So I can't say how the Sato rod compares to TFO rod. I've never fished with a TFO rod, I saw one at a fishing show, it seemed well made, but to stiff for my taste.

All I can tell you is I have made similar kinds of homemade lines and used them with the older TUSA rods and they worked fine. Just not my preferred way of fishing. But others like that style or setup. The only way to know if it suits you is to give it a try.

Good luck.
