I would opine that almost defintely the 20mm on softest would be stiffer than the 18mm on hardest..
Apparently stiffness is proportional to the diameter to the power of 4, whereas stiffness is just linearly related to the "adjustable ARB softness setting" which just determines the sidearm length.
Cheers,
TB

How do you think the 20 mm on the softest setting compares to the 18 mm on medium-hardest setting? As TB suggests, maybe 20 on softest could be a way to start, then having room for more a aggressive setting if you want to?
