I don't want to drop my bike at all...this I know.
If the progressive is harder than the stock when jacked up to meet stock height then I am just wasting my $$$ because lowering my bike is not an option I am interested in.
I watch these guys scraping there pipes and dragging the back fender well on the tire as they hit bumps when riding 2 up after lowering their bikes and I just shake my head.
Also if they do (big if still) have to match the spring to my weight on the progressive shock, then buying a shock off E-bay is going to be a crap shoot.
Think I will sit back and ponder this for a while longer and see what other information comes in before spending the cash.
In the meantime I have some inquires out already for the materials to build an air ride.....will see what comes back on that also.
