Stiffness does not automatically mean brittle. Flexibilty does not automatically mean strength. The toothpick and rubber band analogies are inappropriate.
Looking forward to some first-hand, in-use testing.
I agree 100% testing is needed to make true comparisons. Saying because something is cheaper, you wouldn't buy it and it isn't going to last is silly. Especially coming from someone who says they are going to give an unbiased test.
I used the toothpick and rubber band because they were simple items to express brittle and flexible, no not the best. Let's use metal for both. Using the metal from your springs (leaf or coil) for your engine block would result in low engine life. Same goes the other way. The metal from your engine would not make great springs. In an off road situation, force will not be evenly applied to the ramp. I am arguing not to rule out the more flexible ramp (without an unbiased test) because it may in fact last longer because it can flex and recover instead of snap or crack. I am not saying it will last longer, I don't know! I am saying to stay unbiased. Again I agree that "Stiffness does not automatically mean brittle. Flexibilty does not automatically mean strength." But that possibility does exist and should not be ruled out.
