I was reading here and on the Big Air website that parachutes with air-locks are suppose to provide a softer landing more often than a canopy w/out them. I was looking at the Lotus b/c it looks more student, less performance oriented. Any comments on air-locks? There are a lot in the gear section, most positive. But I figure that people with certain disabilities-bad knees, ankles, back etc.-would be more interested in consistently landing softer than those who are perfectly healthy-not that they want to bounce off the ground or anything. I know that I may be jumping the gun here, seeing that I don't even have my license, but I had to ask.
