4 meters 5 long rod balance point at 1.2 meters heavy

First of all, you ask this question does not match, where the center of gravity point and the rod heavy or not has nothing to do,

If you are asking the center of gravity point of the 4.5 at 1.2, the head of the rod heavy? It's not absolute, the 4.5 is not a big difference in short meters, after all, it's shorter,

Are you looking at rods online to see, yes then you have to pay attention to the fit of the measurement to see if the front and back plugs are removed.

I have seen measured center of gravity rear with counterweight.

Describing the meaning of the center of gravity point, mainly want to express the feel of the rod, the general center of gravity point behind the rod, the head weight of the situation is lighter

Of course, this is not absolute, mainly depends on the design of the rod, the design of the rod, even if the whole rod weighs one or two dozen grams. It will not be absolutely head heavy.
