The Suntech PROSPEC RC 54 medium is a 3-position zoom rod that can be fished at 15'2", 16'6" or 17'8". The recommended tippet range is from 9X to 6X. The rod is a moderately stiff, tip flex rod that will work nicely for keiryu fishing in small streams. For medium to large streams, the PROSPEC RC 63 medium would be a better choice.
Although ideal for keiryu fishing, the rod's stiffness and bend profile are not ideal for tenkara.
