wot you mean, kind of?!??
surely it depends on the size of the drop and the speed at which you approach it.
a decent sized, steep drop being hit at speed will require you to push the wheels to the ground so that you can regain control more quickly.
if hitting a drop to flat at lower speeds then you'll have to pull up/pop front wheel/shift weight back more otherwise your front wheel will drop and the rear will hang on the lip throwing you over the bars.
smaller drops at speed can mostly be run at with your weight shifted back a litle and slightly bent knees/arms to absorb the landing.
get the wheels back on the ground more quickly
