IMO, getting good info out here is what is important. Regardless of what any book says, be prepared to work with facts and laws of physics. The stored energy in any loaded spring is directly proportional to the weight put on it. If the weight is the same, the stored energy is the same. Lemme know if this does not make sense or what the issue is here. Or is the issue with the working with the 90/10 type of shocks? Again, asking not arguing; I am open to learn, RRR. Let us know what the book syas on this matter.
