Nine foot five-weight is the universal size trout rod for the western half of USA. Our store sell more of this size rod than all other sizes of single-hand rods put together. That is because the universal fly rod fish are trout that average from 1 to 5 pounds, and the universal flies are from #4 - #20. A nine foot five-weight rod will fish them all. Four-piece is the universal break-down configuration of rod for travel or domestic use.
"The 590-4 BVK is one of my favorite all around trout rods. It actually performs on par with most rods costing three times as much." MB
