While trying to get myself a rare for "One That Didn't Get Away" achievement I was very aware that I would be fishing for a very long time. In order to reduce the amount of downtime due to deleting the junk fish (aka, "throwing them back") from my already nearly-full bags, I sought out an addon to allow me to only keep certain items.
I found LootFilter, which mostly works, but allows you to add items to a delete list so they are immediately deleted when looting (beware, deletes the whole stack(s), so don't use this once you have *enough* of something).
Now I'm off to catch my 15 pound mud snapper (caught two 12-pounders in the first 37 catches)!
Also, I can't believe this is the first time I've bothered posting here. I've been a long time user and fan of the site. Thanks for everything.
Now what should I do with my second Old Crafty?
EDIT: Caught the mud snapper! Amazingly, it only took 167 casts! Time to go see if my luck will carry over to catching Mr. Pinchy!
