CONE OF FLIGHT: A properly designed guide train will affect, casting distance, accuracy, load distribution, rod torque, sensitivity, and the over all feel of the rod. All of us have been fishing with standard cone of flight guide placement for the last century. It was believed that this offered the smoothest flow of line from the reel to the tip of the rod and that the number of guides was a function of load distribution. If you wanted to cast further the idea was to use less guides to reduce line slap against the guides. The trick was to find the right balance between enough guides to distribute the line across the blank evenly or use less guides to increase casting distance. Fuji then developed the NEW GUIDE CONCEPT which more rapidly chokes the line down to a predetermined choke point and then runs straight through the remaining running guides which are all the same size. The new concept was that line slap against the blank causes more energy loss than line slap against the more slippery guide rings. The sooner you can get the coils of the spool to run straight and true the farther and more accurate it will cast.
