1 1/8 oz. 7' 4-piece mid flex 7.0 fly fishing rod for 4 wt. line.We set out on an adventure to make the world's lightest fly fishing rod. Along the way, we also made the world's best. A few years ago we introduced the Superfine Trout Bum, a 7-foot 4-inch 4-piece that became one of the single best-selling models we ever introduced. Now comes its successor, the Helios Ion 704-4 Mid. This new version offers the same remarkable versatility as a small but powerful pack rod for backcountry fishing and small streams, but as a 4-weight, capable of handling surprisingly big fish. Whether in a western spring creek or a Pennsylvania trout stream, when the cover is thick and the fish are big, this is the rod you need. Built with Helios technology and weighing just 1 1/8 ounce, this rod feels like a feather, but has the backbone to handle 20-inch trout. Like its predecessor, it's destined to become a legendary Orvis rod.
