My wife and I use the DAA posts, for years. And rarely does a moon fly off and I do like to tear around a stage (I had my 2011 rig hit the deck on the weekend during a stage-interesting to say the least)
And anyway I just added more posts so I don't have to worry if one falls off, plus I shamelessly copied MWP and have 2 extra LOMR posts behind my left hip.
The plastic racks look uncomfortable but I've never tried one.
