I'm on the same boat as these fellow fishers. The reason this fish is so unfairly difficult is because we are unable to tell whether we are hooking a pearl eye or a sculptor, thus almost always wasting 400 GP to Double Hook pearl eyes while already being under tight GP management due to having to maintain Fish Eyes. And this leads us to spend a good portion of the (already semi-rare and short) windows waiting to recover GP to Double Hook again.

The most reasonable way you can help us while still maintaining the challenge factor, is by changing the legendary tug on pearl eyes to a medium one. This way we don't have to throw away our GP and be unable to proceed. This is quite sensible considering pearl eye isn't even a particularly large fish.
