Fink Bill 7341 4/5 wt 1 Pc Penta
by Fink
OK - Here is Bill Fink's penta taper. It's a 7'3" 4-5 weight. It is very crisp and accurate a wonderful DF rod. The numbers are the STRIP dimensions ie. the planing form settings. Bill built this as a one piece and I suggest you do the same if you possibly can. Can you do that on a Morgan Mill? Maybe Bill would consider running a two piece taper for the vechicle length or planing form impaired

This rod has a "Tip-heavy" 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.
