spring/shock mounting theory

[blueb8llz]

ok, im trying to get answers from you guys so i dont have to waste my trial and time.
option 1:i have 4 progressive springs and 4 stiff springs on the lowest setting on the arm and middle setting on the shock tower,
option 2:if i was to change springs to all 8 progressive springs and set on the middle setting on the arm and middle setting on the shock tower, and since the 8 progressive springs are not as stiff as option 1, it sits exactly the same, but if i was to lift up the truck with my fingers, itll raise higher than option one since its now on a higher ground clearance setting.
so now my question is, will i be able to trample over taller things, such as mounds of rocks, street curbs, etc...with option 2? im thinkiing yes, because even though they both sit the same height at its rest state, when im going over tall objects, the object will push the arm or bottom of my chassis causing to raise my springs.
but with option 1, the object can lift up my truck any higher because its already at its highest state.
is my theory correct? i really dont wanna have to change out all 8 springs and try it myself , and then have to change them back because my theory was wrong.
thanks
