ok so im goin for 80 fishing, got me a gang of feathers.....i already have 80 cooking banked, so should i just power fish and drop? or bank and get cooking even higher?

I assume you're in Shilo Village, so I'd say bank them. It only takes a few seconds and won't harm your powerfishing process.

bank them :D

Personally I drop my fish... But I'm lazy and already have 99 cooking. I'd say if you'd be getting exp from banking and cooking later, it's worth the time to bank them.

if you want cooking exp, i suggest youd fish monks, since they still faster than sharks, and you get way more cooking exp than those trout
