Fishing is tough there at the moment...need to go super small or super light tackle to catch them, the fish took a beating this season and is very cautious.
Not taking anything away from you or your abilities, but, you most probably had way many fish on the line, you just didn't know it, they take the lures very very softly off late, 95% of the time on the drop, or just when it hits the bottom, next time if it feels like anything extra is added (or like you're slightly stuck) strike! The big ones mostly gets busted on sight fishing......
I'll most probs pop in there 2day, in between the duties for the day..... will report if I did manage to go.
