Lever-arm shocks, as good as they may be (?) don't have the instantaneous (change of direction) dampening that a good tube shock has.
Really? Why is that?

If you've ever taken one apart __(I know; what is WRONG with me?!)__ you'll see that the two (2) pistons operate from a central rocker-arm, or pivot. It takes more than a few degrees of shaft rotation to get them stroking in their bores (one goes in, while the other goes out). The moving piston(s) is what forces the oil, through the respective valves, into the other bore (chamber).
You can usually feel the deadband when operating a shock by hand; just move it up and down a little when the link is disconnected and the shock is still mounted.
I mean they work, but have you seen any used in design lately? /bcforum/images/%%GRAEMLIN_URL%%/wink.gif
Modern tube shocks are a lot more efficient, and when tuned for sporting work (like Konis or Bilstein) respond much quicker in transient manoeuvres (say, a slalom).
