Extra Large Diameter Bamboo Culms
Extra large diameter bamboo culms are 55-65mm in diameter by 12'-0" long. These are the prefered culms for large flyrods in an 8 weight or above, including two handed spey rods. One could certainly make a lighter rod with XL poles, but more planing will be required. Some quad makers use them because the large diameter allows for wider flat sections on the strips. The wall thickness is greater but they typically have more cosmetic flaws then the standard poles. The larger poles are not as common and represent only about 20% of our annual inventory.
XL poles are sold in bundles of 8 culms.
