need some education I see "small stream" bamboo rods offered for sale....rebuilt from old mass market bamboo rods. They are usually built from the mid and tip sections into a 6 ft rod. Most look good with new finish and hardware but wondering how they would cast. Has anyone had experience with this or an opinion. I am also wondering about what weight line they would cast? For example a 3 ' mid and 3' tip section from a 6 wt rod. Thanks .
