Did you manage to get the new fishing rod? Is it better than Serenity?
I found the update to be more fun after getting really high. Haven't found all of the chocobos (surprised I actually haven't found more) 2 more moogles and that damn fishing rod and I got it all.
Due to me platinum the game, I only bothered to fish like about 10 times. I bought the new one plus the reel and it seems "slightly" better, not a big difference on much but could be useful if you are still aiming for the trophy.
