There are thousands of possible reasons for a reserve hesitation that are NOT the fault of the manufacturer. I'm not saying that it cannot possibly ever be the fault of the manufacturer, but I AM saying that you're jumping to conclusions awfully fast. And Aerodyne does indicate why an excessive long closing loop is bad: it doesn't compress the pilot chute fully and reduces its effectiveness significantly.
If we as riggers in the world are to improve the safety of skydiving equipment everywhere, we need to keep an open mind AND be thorough, detailed and open in our analysis. Baseless accusations are worth less than the electricity used to transmit them. If you want me to take you seriously, show what that rig is exactly. What reserve is in it? What main is it in? What AAD is in it? What length is the closing loop? What size exactly is the rig? How was it packed? How was it tested? What exactly did you observe in the failures? Where did stuff catch that wasn't supposed to catch? It's like high school math, just writing down the final number is not enough, you've got to show the work done.
Pretty please with sugar on top, show the f*ing details. Otherwise, I'm bringing the beer to Baksteen's popcorn party.
