Here is the non-myth. The line ratings on most rods do not indicate how much weight the rod will lift. The rating on the rod indicates the most suitable breaking strain line to use on the rod, with a correct drag for that line set on the reel. The rating is designed to achieve a working curve in the rod, without reaching a lock-up point.
To explain further – a rod should be designed to achieve two tasks:
One task is to act as a shock absorber. The rod should bend and flex as the fish lunges and darts in its efforts to escape. This shock absorption helps to guard against hooks pulling out, or line breaking.
The second task a rod should achieve is to provide lift. This is a rod’s working curve. A bent rod tries to recover its shape, i.e. straighten up. This provides lift, helping the angler recover line.
The lock-up point is the point at which a rod will bend no further without breaking.
