Tip-loaded (fast action)
This rod has a "Tip-loaded (fast action)" stress profile. Stress varies significantly across the rod. Some sections work much harder than others, creating a pronounced action character. The peak stress is above the safe threshold for bamboo — this taper may be at risk of developing a permanent set under heavy loading.
