Second, reels with fresh- and saltwater origins can contrast greatly in their overall weight. For instance, the Orvis Vortex reel is a superb large-arbor saltwater design, which the company has also shrunk down to a 5/6-line-size reel that hits a hefty 9.6 ounces. The Orvis Battenkill Large Arbor III, built from the start as a trout reel for similar line sizes, weighs only 5 1/4 ounces. The heavier reel would be great on a bonefish flat, but putting one on a light trout rod would be like towing a pontoon boat with a Ferrari. In general, a satisfactory large-arbor reel for 5-weight trout rods-a common yardstick-will be in the 4- to 6-ounce range with an overall diameter of 3 1/4 to 3 1/2 inches, and with a capacity of 75 to 125 yards of 20-pound-test Dacron backing plus fly line. You'll see some variation on both sides of those specs, but that's enough to start you shopping. Which is exactly what I'm doing myself. After some 30 years of service, my lovely traditional British reels are going on the shelf. It's large-arbor time.
