Just so you guys know...my first malfunction was caused by my packing for sure....I was having hard inconsistent openings so I added an extra rubber band stow to the nose slider....it helped so I added another stow....it helped so I added another...after like 4 stow wraps the canopy opened but the nose slider held the nose completely closed and never released. There were other canopies in the air with me and it didn't look like I was descending too fast so rode it in to kind of a hard landing. So I ditched that idea. Then I had an entanglement due to what I believed was lines not straight on packing and rode that in with no problem. My last one the canopy opened but the slider would not pump down and was stuck at the skirt band holding it closed....I pulled the toggles as hard as I could as a last try but the back of the canopy folded under and I went into a backwards spin at probly 35 mph rate of descent at least. Definitely cut that one away. The canopy was burned up somewhat so I sold it to a friend who had it repaired and jumped it for quite a while without a problem.
