Leonard 38 7042

Since people were requesting it figured I might as well post this to list this is the taper I used to build my dad's rod (I think I got it from an old Planing Form??) I got several others that I think were actually confused with 38L and 38H models. Leonard 38 ACM c. 1960 7'0" 2 pc 4 wt (measured over bare bamboo)

This rod has a "Balanced / moderate action" stress profile. Stress varies significantly across the rod. Some sections work much harder than others, creating a pronounced action character. Peak stress is in the optimal working range. The rod is efficiently utilizing the bamboo's strength.
