I use to tear apart ink pens for the springs. They work well.
But you need to FLING THE SPRING!.
Yep, FLING THE SPRING!
The new UL rods and one pound test are performance at a peak. With light line, all you do is watch how the line leaves the last eyelet. If it loosens, set the hook! If it tightens, set the hook! If it acts weird, Set the Hook!
Fling The Spring!
On hits, swim byes etc...the line will be effected prior to the springs. Once you fling the spring, you won't go back. The results are phenominal.
Give it a try if you dare.
