Alleycat , (we met once at Wello about 12 months ago I think ) I don't think you are on your own . I too fish regularly as often as 3 times per week and am also struggling for some decent catches this year.
Methods and tactics do not appear to be getting the same results as last year and recently I have been experienting with some different methods and locations with average success.
Maybe the fish are smarter or they just aren't there.
Just got to keep trying . it's always to good to get on the water though regardless.
