Well the correct method of balancing rods is not just laying them on a gram scale. You need two scales and some polished round stock stands that you tare out. This gives you the weight of both the small and big end of the rod. Both of which are important and should be adjusted as needed. The rod is set horizontally with the rods supporting the ID top of each end. Think of it this way. You can weight you bike on a truck scale and get the total mass. But if you put the front and rear wheel on its own scale you get total mass plus front end weight and rear end weight. So you have the F/R balance numbers.
