<P> As of both IM and modulus, the higher rating, the stiffer the carbon fibres in the rod, together with this stiffness, the carbon also becomes more brittle and show more wear over time . </P> <P> Spin casting rods are rods designed to hold a spin casting reel, which are normally mounted above the handle . Spin casting rods also have small eyes and, frequently, a forefinger grip trigger . They are very similar to bait casting rods, to the point where either type of reel may be used on a particular rod . While rods were at one time offered as specific "spin casting" or "bait casting" rods, this has become uncommon, as the rod design is suited to either fishing style, and today they are generally called simply "casting rods", and are usually offered with no distinction as to which style they are best suited for in use . Casting rods are typically viewed as somewhat more powerful than their spinning rod counterparts--they can use heavier line and can handle heavier cover . </P> <P> Spinning rods are made from graphite or fiberglass with a cork or PVC foam handle, and tend to be between 5 and 8.5 feet (1.5--2.6 m) in length . Typically, spinning rods have anywhere from 5 - 8 guides arranged along the underside of the rod to help control the line . The eyes decrease in size from the handle to the tip, with the one nearest the handle usually much larger than the rest to allow less friction as the coiled line comes off the reel, and to gather the very large loops of line that come off the spinning reel's spool . Unlike bait casting and spin casting reels, the spinning reel hangs beneath the rod rather than sitting on top, and is held in place with a sliding or locking reel seat . The fisherman's second and third fingers straddle the "leg" of the reel where it is attached to the reel seat on the rod, and the weight of the reel hangs beneath the rod, which makes for a more comfortable way to fish for extended periods . This also allows the rod to be held in the fisherman's dominant hand (the handle on most modern spinning reels is reversible) which greatly increases control and nuance applied to the rod itself . Spinning rods and reels are widely used in fishing for popular North American sport fish including bass, trout, pike and walleye . Popular targets for spinning in the UK and European continent are pike, perch, eel and zander (walleye). Longer spinning rods with elongated grip handles for two - handed casting are frequently employed for saltwater or steelhead and salmon fishing . Spinning rods are also widely used for trolling and still fishing with live bait . </P> <P> These rods are used to fish for smaller species, they provide more sport with larger fish, or to enable fishing with lighter line and smaller lures . Though the term is commonly used to refer to spinning or spin - cast rods and tackle, fly rods in smaller line weights (size #0--#3) have also long been utilized for ultra-light fishing, as well as to protect the thin - diameter, lightweight end section of leader, or tippet, used in this type of angling . </P>
