<font color='#0000FF'>Hi
Over the head for me too. I wear a weight belt though so that helps.
The main method I use is too clip off the long hose to my right DRing. Then if I slip the left strap off the shoulder (to just before the dump) I then use my long hose to pull the right strap off and my right arm out. Easy
Oh, don't forget to undo the waste strap first
