The description is pretty vague, and I still haven't figured out what it really does. Does it:

A) increase the probability of getting higher lvl fish (as in good for hunting star fish)

B) bigger chance to get heavier fish

and how big is the increase? I have used tried using it for hunting i70 fish for leveling my cul desynth, but I can't say it's been of any help whatsoever.



Also, what about the different Hooksets, does any of them work on fish released before HW? Recently I failed hooking a vanilla 2 star fish using the powerful hookset, so I figured that the Precision one would work; guess what, it didn't :P. Thanks in advance!
