throwing your weight forward is NOT a useful skid. it's a skidcomp skid, or a learners skid. it unweights the back wheel too much. the balls over the stem thing should be happening only for fun or in the learning stages, in my opinion.

in high rpm, skipping is very very importnat, and is very useful to power down too. it involves kicking up the back wheel (for lack of better term) freezing it and setting it back down. can cut your speed in half used properly.

learn to skip, for you, for your knees, for your tires.

now, who wants to have a skidcomp? :-D
