In our "Other Stats" department, we note that the TDZL691MHXB is very light for its power at only 4.2 ounces, but a bit tip heavy balancing at 9.5 inches above the centerline of the reel seat. By comparison, the STZ671MHFBA (a rod that is 2" shorter) is the same weight, but better balanced. In an effort to quantify this "tip-heavy" feeling even more, we're introducing a new stat into our lab tests. By weighing the tip of the rod when holding it at centerline of the reel seat, and multiplying this value against the distance from this point to the rod's tip, we can calculate the approximate torque in foot pounds it takes to hold the rod horizontal.

The idea here is to develop another relative data point (Balancing Torque) to help us compare the "tip-heaviness" feel one rod has over another. In the case of the TDZL691MHXB, its Balancing Torque (BT) calculates to 0.187. The STZ671MHFBA has a BT value of 0.142. Can we discern the difference between these two rods? Not really. In hand, they feel equally balanced. It's not until we try to find the actual balance point of each rod that we can discern a difference.
Naturally, since this is a new measurement for us, the rods that are no longer in our vault will not have this datapoint for comparison, but the hope is, as our data inventory grows, these numbers will become more meaningful. With that intent in mind, we will discontinue reporting on each rod's spine as we've come to find over the past couple of years, the relative importance of his information in a real world fishing scenario is minimal at best. In other words, we could not discern any benefits one way or another in the location of a built rod's spine while fishing, so this datapoint has become immaterial to us.
