Casting rods are equipped with curve technology that rotates the guides from the top of the rod to the bottom making it the most natural comfortable experience. All rod blanks have a spine, which is the point where the rod naturally wants to bend. Rods that have straight guides are aligned on top of the spine and multiple problems occur from this, when trying to balance on a very thin pendulum the only time the rods true spine is being utilized is when the line is directly away from you in a straight line with the blank. Anytime any pressure is put on the rod the line breaks over to the left or right, torquing your blank and not remotely utilizing the purpose of the spine. This torque structurally wears a blank down as well as effects comfortably while fishing, the reel on top naturally wants to make the rod rotate under, this is a problem that is hardly noticed until fishing with a curved rod. Curved guides keep constant downward pressure on your hand and the spine no matter how far left or right the tip of your rod is pulled while maintaining in line with your spine. A simple test at home and you will be able to convince yourself, take a casting rod with straight guides with your reel on and line fed through the guides. Hold the lure or line in one hand and your rod in the other. Keep your hand stationary with the rod and put pressure pulling the line to you to bow the rod up. Once bow'd up move the line left to right maintaining pressure the entire time and notice how the guides are twisting your blank as well a popping over the spine while also adding torque to your wrist.
Guide Lock Technology
Rods after a few years seem to always break a few guides. Most of the time there is no apparent reason why, your fishing and a guide just breaks and it is passed off that maybe it got hit somewhere. The amount of repairs I have done to individuals rods outside my own with this issue is never ending. In nearly all these cases it has been linked to the same thing, water creating rust points under glue. Guides are glued over the wrap leaving points in which water can either get under the glue over time or cause that point to rust. This type of problem is seen very often on double foot guides and is not an if it will happen, but when. Guide Lock is the process in which glue is connected in between the guides, locking in at those fragile points shedding water away and allowing no where for it to sit. Besides the fact of keeping your guides brand new it also keeps your glue from wearing down and separating from your blank overtime. With Guide Lock Technology paired with a Crow Series the only problem you will have is creating an excuse to buy a new rod.
