To change the length of the rods, we cut the blanks from the but end. Therefore the tip is the same on all the rods. That being said, there is a difference in backbone for the longer vs shorter rods. A 36″ rod will have 8 more inches of backbone than a 28″ rod. For most applications on a noodle rod this won’t have much of an impact. But for more backbone driven rods, like the commander, we typically won’t go shorter than 32″ so their is still ample backbone for the big fish. I personally think 32″ is the sweet spot for our rods. It is what I have all my rods in, even though it is slightly too long for my Otter Cottage. Going back to the original issue though, the performance of your tip vs your friends is most likely being affected by lure and line choice. A heavier lure will bog the tip down more, where a lighter tip will allow more tip movement at the bite. Also braid lines tend to float a bit which will make the small jigs seem lighter, and mono sinks, making the jigs seem slightly heavier.
