Review: Great line - Super strong line. Been using now for few weeks.
Review: The best line I've used period. - I've tried every line made! This is by far the most flexible and strong I've ever used! The nice thing is despite it's strength it still has flexible to it so you are less likely to snap it. It cast excellent with virtually zero backlash or issues at the spool. It is so clear I often can't see it in the air after the cast. Its pricey but you are buying Seguars best line straight from Japan.. Its the only line I use especially for Trout or line shy species. Buy with confidence.

### ⭐⭐⭐⭐⭐ Impressive fishing line for novices and experienced anglers
*by S***E on February 6, 2025*

I fall into the category of a "novice" fisherman, so the concept of fluorocarbon was new to me. For my fellow newbies, here's the summary. Fluorocarbon is nearly invisible underwater, so unlike regular fishing line (monofilament) it's much less likely to spook fish. Fluorocarbon is also resistant to abrasion, as well as to stretching, which makes it more sensitive to detecting fish bits. Seaguar is the company that invented it in the early 1970s and they still do it better than others. The first thing you'll notice about fluorocarbon is how thin it is. This 5lb test line has a diameter of about half the diameter of a regular monofilament line for the same strength. That's because flurocarbon is denser in general, and Seaguars technology allows even thinner and stronger line. This R18 line is softer and more manageable than some of their more advanced lines so it's not a bad choice for beginners and pros alike. It's easy to string onto a reel, easy to cast with, and easy to tie good knots. I appreciate that Seaguar has kept these made in Japan, and the quality shows.
