A lot of good info here. I like the idea of a DZO manual. What on this list do you feel Rook is neglecting?
P.S. If you are scared of getting hit by a swooper, stay away from the high performance landing area! If there is not one, make one. If there is not enough room... No swooping (I will not be there as the swoop is my favorite part of the skydive). At my dropzone it is a constant battle between the swoop/non-swoop crowd. There is plenty of room for all of us. Yet still drama! My high score on Donkey Kong is 239,400.
