Big Fish and you: What bait is needed when to land the big one

[LlenCoram]

jeeze, just got the Rivet Oyster from Vesper Bay in western thanalan. i tried yumizuno for 30 minutes, then switch to heavy iron jig cause i was thinking oysters are on the bottom. got a miss so i knew it was there. then another 8 misses on it for the next 45min. and i'm at 356 gathering 292 perception.
finally got it 7:31am, fair weather
only 12.0 ilms

Wow. Glad to know the rod is only barely what we need.
