It’s interesting, I watched that line comparison video and to me it could support the opposite point – the fluoro/mono difference looks very subtle at best. The braid visibility is obviously in a whole different ballpark but even then I catch plenty of pike and bass on straight braid. Also, the 30 lb mono example was much closer to the camera than the others.
IMO, regardless of line type, any open water break-off (not cut-off) of 20 lb test line is user error – bad knot, worn out line, bad drag setting. If in doubt, just try lifting a 20 lb dumbbell at the end of a fishing rod to see what it feels like. Our line strengths are overkill, but it buys us some forgiveness for user error and wear.
Our lures tend to be laughably non-realistic – gaudy neon colours, violent flapping/wobbling, rattles, dangling hooks, etc. It’s hard to believe that a fish would succumb to all that trickery (dragged behind a puttering outboard and giant cannonball, no less), then turn up its nose because a tiny strand of clear plastic has the wrong chemical formulation lol. But who knows…
