I can't tell you where these came from - but I can show you what they look like!
Right, so this is a bit of an unusual one. A few months ago, I got talking to a contact who has, shall we say, interesting connections in the European competition fishing world. I'm deliberately being vague here - because apparently that's how it works in these circles. You don't ask too many questions, you don't broadcast where the patterns came from, and you definitely don't post a step-by-step breakdown on social media.
