I see. The 120s are the same diameter, but just under 2 inches taller. The 130s are 3/4 inch larger diameter, but 1/2 inch shorter. So the 130s are actually close to the same length as an 80.
Why is it so difficult to trim different tanks, than somebody is used to? Would it not simply be going through the trouble of trimming from the beginning again? Or is that the problem, not wanting to start from scratch again. I truly am curious on this as I will probably change my tanks evenutally and want to know what to expect.
On another note. I would think going to a tank that is a little longer would be easier than one that is shorter as it would spread the balance point of the tank out a little more. For example, if I put a 1 foot steel rod across my finger (like a see-saw) it would be harder to balance once I found the balance point than a steel rod that was say 3 feet long. The balance shifts of the shorter rod would be quicker and more pronounced than ones of the longer rod. Just curious all around.
