Orvis Clearwater Extra Fly Line Fly Fishing Spools - Carry an extra spool loaded with a second line so you can change strategies as the conditions dictate. Add an extra Clearwater spool to your bag and set yourself up with a second fly line option when the on-water situation calls for a change. Rig extra spools with different weight lines for a quick, economical way to use the same reel frame on different-weight rods. If you are fishing only one rod, use interchangeable spools to switch quickly from a sink tip streamer rig to a floating line when the dry fly bite turns on. 3.4in diameter. Die-cast frame is protected by a durable powder-coat finish.
