Don't forget a few Blobs icky!

Fred Stillwater Angler sells the best. His bloodworm variants are deadly too.
As for naturals, some terrestrials like Foam beetles, Hawthorn Fly and Daddies and of course Mayflies. Some of your Klinkhammers might do well if there's any surface feeding, ditto Suspender Buzzers and Shipmans.
If things are tough, small dull patterns like a Kate McClaren fished very slow can work. It's not all fluorescent fritz and pink marabou!
Have a look in the returns book, most people write down what worked for them and speak to the staff, they want you to catch fish and return another day.
Hope you all have a good day.
