Tenkara level lines are lines specifically used for casting with tenkara which have a level diameter and can be cut at any length. The best tenkara level lines: high visibility, little memory, the right stiffness and density for casting, and easy to keep off the water for drag-free drifts.

Benefits of tenkara level lines:
- Lighter weight, which allows anglers to keep the line off the water as the fly drifts on the other side of multiple currents. This provides for very good drifts.

- Versatility, where an angler can cut whatever length of line is desired or join lines together. 

- Economics, A spool contains 65 feet (20m), and allows you to make 4 or 5 lines, for a lower cost per line. 

Things to keep in mind: level lines require a slightly faster casting stroke, with very little pause on the back cast, and take more getting used to casting due to their light weight. Also, they do not have a pre-tied loop for girth-hitching to the rod tip.
