How many times can you really downsize in a container before it become to soft? I have heard many answers. between 1 and 3 sizes depending on cells, closing loop length, closing loop placement, canopy pack volume, manufacturer, ect. anyone who has actually tested this would be much appreciated.to be more specific, I have a Dolphin D-6 and a 9-cell 260. I want a Sabre2 230. any educated suggestions?
