Fly Line Densities Fly lines are available in different densities to accommodate different circumstances. The density of the line will determine whether the line will float on the surface or sink. Floating fly lines have the lowest density, Intermediate fly lines have a neutral density whilst sinking fly lines have the greatest density. Floating lines are the most commonly used as the angler is able present a dry fly on the surface or a wet fly below the surface. If you are new to Fly Fishing we recommend you purchase a floating fly line to start off with, increasing your collection as you become more experienced in fly fishing. With this in mind make sure you can easily obtain spare spools for your fly reel when choosing your reel so that you can easily change the fly line over when required. All fly reels listed on this website have easily obtainable spare spools. For reaching fish in deeper water you will require an Intermediate or Sinking line. Intermediate lines will sink very slowly whilst a sinking line will sink at speed enabling the angler to present the fly on the bottom quickly, ideal for deep water fly fishing or in extreme heat where the fish will be hard on the bottom in cooler water. Some sinking fly lines are available in different sink rates, this is usually measured in IPS (Inches Per Second). the chart above clearly illustrating the different profiles of line available, the lines shown are from the excellent Cortland series of fly lines but illustrates the general densities of today's lines. Looking from left to right you will firstly notice the 'Floating Line' floating on the surface. You will then notice the 'Intermediate tip', this is essentially a floating line with an intermediate clear tip. Next to that you will see the 'Sink Tip', again a floating line, this time with a sinking tip. next to that the the 'Cortland QD' (Quick Density) and lastly the 'Sinking line'.
