hi there ed,
that's wonderful!!! it's such a familiar feeling. i don't know anything about your main but you have to be able to land 'em. i've heard folks say that toggle pressure can go up with larger canopies because you're moving more material (with more resistance) but i don't really know.
i was surprised by the toggle pressure on my main (210 Silhouette, very similar to a Navigator)....not bad at all but more than i expected. the best (enough for feedback, but i could hold it in deep brakes all day long) was my cruisair....loved that canopy. i don't think anything is as easy to turn as a Paracommander though.
i'm amazed at the choices of equipment today.......if you have it available try some different canopies......i'm sure you can find something that works. i'll put a vote in for the Silhouette if you can try one....mines pretty tame by today's standards.
i like the hand deploy stories......it used to be kind of a known step that people often prepared for (i also practiced at home about a hundred times i bet before the big day) and i still remember that jump......new (to me) gear.....first piggy-back rig (Wonderhog II, with belly band and 3 ring release) and first square jump. i threw that pilot chute with everything i had and i was surprised by the noise under canopy (and the amazing performance of a Strato-Star).
hope your son heals well!!!
