RIO’s Cranky Kit is a quick, convenient fly line spooling/storage station that includes one RIO Cranky (featuring ergonomically shaped handles for a smooth, comfortable operation) and a RIO fly line spool.
With a RIO Cranky Kit, anglers can change lines quickly and efficiently as fishing conditions change. Simply wind the line off the reel through the rod on to the fly line spool that is provided, unloop the line from the backing, then loop the new line to the backing and wind the new line on to the reel. With this technique anglers will not need to restring the rod.
In addition, with a few extra fly line spools, anglers can build a convenient fly line storage system and library.
