I was able to do a few jumps with a new, simpler and apparently improved packing technique. I followed the guidelines presented to me a long time ago during packing courses as a student, PD's recommendations on how to pack not only a Katana, but all of their canopies and additional suggestions presented here in the DZ.com forum.
I stopped "tucking" my nose, as PD stated that this may cause off-heading openings and subsequently (in my opinion) the increased potential for twisting up. I also stopped rolling the tail "tight" and put only a few 1-2 inch rolls in the tail before lying it down on the ground. This, at least in my mind, seems to help prevent the canopy from spinning once out of the bag immediately prior to inflation.
Anyway, the recommendations were immensely helpful and I appreciate them all. I'm now looking at symmetric, on-heading openings and feel more in control of the canopy throughout it process.
Thanks!
