    What will suit me better? Digressive or progressive shocks if I do a lot of highway, a bit of city and a smaller bit of rock climbing.

    I was going to get the Icons but they charge extra for 700lb springs so I was then thinking Kings...please help.

    I think digressive is the way to go but need a good bump stop if you hit them often. They slam them hard due to nature of the valving.

    Will I be hitting them at high or low speeds?

    Progressive is probably better in all the instances you list.

    A progressive is going to be softer on the smaller pumps, and stiffen up on the faster, larger bumps, whereas a digressive is opposite. A progressive suspension gives a softer street ride, but protects from falling off ledges, or rocks by stiffening up the last half (or so) of the travel.

    And when I'm driving on the FWY, is it going to be too stiff?

    Nope, street driving will be near stock for both pro and digressive valving, digressive valving will be softer if you hit a speed bump at speed, progressive will be softer slower.

    Last question: For rock crawling, would having a digressive shock be a disadvantage?

    numbers of posts in the past three years say yes. although it seems like ICON is currently working on changing that perception.

    The disadvantage would be that the ride is harsher as you crawl over the rocks?

    i think it won't flex as easy on smaller slower rocks. the flip side is if you're crawling and hit a big rock it will flex better then progressive.

    Even if you're driving at a slow pace you can achieve fast shaft speed on the shock by hitting a big rock and it will absorb it better then progressive.

    What about not wanting to slow down for speed bumps :)
