The line weight is dictated by the taper you create in the shafts. This is predetermined on a lot of rods with published tapers. But like Bill mentioned longer and heavier rods generally take heavier line weights to make them flex. The thing that fascinated me with bamboo is that you can make any rod you wish with the same culm, if you buy a plastic blank, it is what it is, no changing it. Additionally, you can take a given taper and lengthen it or shorten the length or change the line wt requirement with some minor calculations made by programs like Hexrod.I have so many questions, but I'll limit it to the one that interests me the most. How do you guage which weight fly line the rod is rated for? Is this predetermined before the actual build? Two questions, I guess.
