The FMX Keiryu stiff 54 is a 40 penny rod, which is substantially more than the Nissin 540ZX medium (30 pennies) and the Suntech Field Master 53 (33 pennies). The rod is lighter and not quite as stiff as the Nissin 540ZX stiff (44 pennies), making it more pleasant to to fish with (whether tenkara or keiryu). It would be a nice upgrade from the Nissin 540ZX medium. It is higher quality rod and more capable as well. The Nissin 540ZX medium is rated for a maximum of 6X tippet, while the FMX Keiryu stiff is rated for 5X. What can you catch with it? Anything you can catch with 5X tippet.
