Andrew, one of the founders of Fly Lab (fly.fish), joined the show to talk about building an unbiased gear-review platform for fly anglers, but the conversation that stuck with me was about something else entirely: the small, repetitive habits that separate anglers who consistently land big trout from anglers who occasionally get lucky. He called them his "religious" fly fishing habits, and once he broke them down, they made a lot of sense.
Check Your Knots Like It's a Religion
Andrew's first rule was almost embarrassingly simple: check your knots constantly. Not once at the start of the day, but continually, every time you change flies, after a hard hookset, after a fish, after a snag on brush. His reasoning is that big fish don't come around often enough to afford losing one to a knot you could have caught. If you hook a lot of big fish and rarely lose them, it's usually not luck. It's because the knot-check became automatic instead of an afterthought you remember only after you've already lost a fish at the net.
Run Your Fishing Through a Kaizen Process
Andrew borrowed a term from manufacturing: Kaizen, the Toyota philosophy of continuous, incremental process improvement. He treats fishing the same way. Catching a big fish, in his words, is mechanical and process-oriented. You have a process for how you approach water, how you read a fish, how you present a fly. When something doesn't work, or when you learn something new on the water, you fold that observation back into your process for next time. The anglers who plateau tend to be the ones who fish the same way every time regardless of what the last outing taught them.

Watch for the Confidence Drop-Off
One of the more useful things Andrew flagged is a pattern he's watched play out in other anglers' heads: the confidence drop-off. An angler ties on a streamer color or pattern, doesn't get a take in the first few casts, and quietly decides that color "doesn't work today." From that point on, they fish it half-heartedly. The retrieve gets sloppier, the presentation gets less precise, and the pattern fails, not because the fish rejected it, but because the angler stopped fishing it properly. He's watched this happen enough times to call it out by name. If you're going to fish a fly, fish it with full conviction until you have an actual reason, not a feeling, to change it.
Be Sneaky Before You Need To Be
The last habit ties the others together: build stealth into your approach as a default, not a reaction. Anglers often start moving carefully and paying close attention only after they've already spooked a fish or two. By then it's too late for that particular fish. Andrew's advice is to treat careful wading, quiet approaches, and close observation of rise forms and feeding lanes as part of your standard operating procedure on every single fish, not a mode you switch into after a mistake.
Make Informed Decisions About What's In Your Box
Andrew's day job, building Fly Lab into a members-only source of unbiased gear reviews, comes from the same discipline. He got tired of watching anglers get steered toward rods and reels through pay-to-play magazine reviews, and built a model where reviewers have no financial stake in which brand wins. The connection to the "religious habits" idea isn't a stretch: a good process depends on trusting your gear the same way it depends on trusting your knots. If you're constantly second-guessing whether your rod, line, or fly choice is the right one, that uncertainty bleeds into your presentation the same way a lost confidence in a streamer color does.
