The perfect bamboo rod doesn't exist…but the perfect rod for you does
Let’s get nerdy for a minute. These are the major factors all rodmakers -- woodworkers and machinists -- must consider when constructing a rod:
Power is a rod's resistance to bending under pressure and is derived from the rigidity of the blank. Thicker or stiffer blanks will increase the power of a bamboo rod.
Action is where that bend occurs along the rod's length and ranges from slow to ultra fast (slow rods bend closer to the handle, fast ones near the tip). Bamboo generally has a slower action than the springier graphite or fiberglass.
Weight actually refers to the weight of the fly line that should be used with the rod, and is measured by the first 30 feet of line. This is much less concrete than the previous two factors.
Graphite is strong, light, and tough. It's also mass-produced, making top quality rods affordable to anyone. Handcrafting makes modern bamboo rods more expensive, but also more treasured by the fishermen who keep a mental magazine of each rod's nuanced action.
