It Depends
The lure wieght is the the best wieght for the task you are trying to accomplish.
Do you want it to go far or be accurate or to get to your target, the fish as fast as possible.
It all depends on what you are doing with the rod.
THe whole kink is that the diameter of the rods parabellem is changing at a ver complex algorithum rate. Not only does the kinetic energy depend on the lure wieght but also on the line drag, the guide drag, the angle of intersection for line exiting the reel spool and the bigest factor is the person behind the rod.
What it all boils down to is does it feel good and do what you want? If so it most likly is good.
If someone has more time than I have here is the bricks and morter. Go develop a finite analysis and let us know how it works.
Call me when you figure it out,
