It happens buddy. I went nearly 2 seasons on a large water just catching the odd bream.
Have you got confidence in a. your spots, b. your rigs and c. Bait???
I very gone back to a rig I have every confidence in, check. Bait is good, but always changing pop up colour on the snowman.
So just leaves spot, which is mainly down to watercraft & arguably a bit of luck.
In the past I'd be quick to change everything, big mistake.
Just small tweaks can make all the difference along with time at the water, you'll unlock the puzzle soon enough.
