I think too many people are reading way to much into me talking ill of one jump in the park. If that single jump rescued you from a roving band of wolves and raised you, I understand.
My question above is a theoretical one, based solely on curiousity. If I've reached my quota, my apologies.
I want a cartoon based on a jump rescuing a fully grown man from a pack of wolves, I think that would be really sweet.
I took the question as you meant it I think, I'd already forgotten about that stupid jump. I like suspension a lot, geek out on it a bit.
Short answer to your 100lb/1000lb question is that it depends what you bought. Tokens basically are to address exactly what we're talking about. Volume adjustable air cans in general are for this. To my knowledge, it is very difficult to achieve with a metal spring, but I could be off base on that one. Non-adjustable volume air cans may as well be a metal spring as your stuck with whatever spring rate progression got engineered in.
Valving(as in size of valve orifices) can play big role on the damping side. Think of the engineers valving choice as the spectrum of adjustment they have given the user. For example, the vivid coil has both an M and an L valve setup. I have an M and wish I had an L. With a rear shock it's important to remember the rabbit hole can be quite deep as a lot depends on the linkage design, which dictates the spring rate and valving chosen by a bunch of engineers who may or may not have gotten it right in the first place.
