Best-of guide
Right, here's the lot. Every bit of mainline we've dug into, ranked by our on-paper score — that's our own desk research on specs, build and price across five things: product quality, performance, how much it helps you catch, ease of use and value for money. We haven't bank-tested these, so treat it as a smart shortlist, not gospel.
Top of the pile right now: Preston Innovations Reflo Powerline Mono (9.1/10), Preston Innovations Reflo Power Line (9/10) and Gardner Tackle GT-HD Line (9/10). Tap into any review for the full lowdown, the comparison and a buying checklist.
Top tip: match the kit to how and where you actually fish before chasing the highest number. A cracking bit of gear for big open waters can be overkill on a snug club pond. How we score.
