No, think about what I am saying here. You do not want to change the grain weight or length of the tip you are casting. This is to keep your casting stroke the same no matter what tip you have on. You adjust the length of the t-14 for the depth and current speed of the water you are fishing. 10 feet of t-14 is going to fish deeper and/or faster water than 5 feet. It doesn't matter what the overall grain weight of the tip is.
