I am currently jumping a Jedei 136, having just competed my first year of skydiving. It is loaded at 1.18, and I intend to jump it until around 400-500 jumps, where I will probably look at like a Samurai 120. I started jumping the Jedei at around 100 jumps, and some people questioned my choice at first, but I decided that it was an acceptable wing loading and I would be extremely careful, and work my way into the canopy, flying traditional patterns and landings until I had at least 200 jumps on it.
I wanted an elliptical canopy because I like the reponsiveness and enjoy flying it agressively on higher opening jumps, plus would like to learn how to swoop over time.
I am only 25, a USPA Coach and have a little over a year in the sport, so take this for what it is worth. I would recommend that if a licensed skydiver is really adamant about getting a more aggressive canopy at lower jump numbers, I would try to compromise with him or her and reach an acceptable middle ground. Instead of jumping a VX or crossbraced canopy, I would try and find them a Stiletto, Vengence or Crossfire (still a powerful canopy) at a lower wing loading, say mabye 1.2 or so. I would try relay what I was taught, and encourage them to fly it gently at first, and gradually take small steps toward more high performance landings, while maintaining the same wing loading. I will be the first to admit that one reason I bought the Jedei was that I thought it was "cooler" to tell people I flew that rather than a Sabre or something. So far I have been ok with it, though I know it will take more time before I can even begin to practice higher performance landings with it. Sometimes for a younger skydiver I understand that pride and ego can get in the way of better judgement. I am enjoying my Coach rating and like to teach groundschool and do Coach jumps with younger skydivers because I feel I can relate to them better, and help them work their way into the sport. Usually we conduct our FJC outside, and I will intentionally stop and let the new students watch the jumpers land so I can tie it into the canopy control portion of the course. It comes as no suprise that the younger jumpers are most impressed by the swoopers and the faster canopies. Because I cannot stop them from doing what they want to after they get their A, perhaps it is best to talk to them on their level, and meet them half way. Again, I know i'm Coach nobody, with 150 jumps, so take this with a grain of salt.
