I am thinking about using a 6" quickburst D bag for my dual deploy rocket, they look nice but this will be my first D bag so I dont really know. I would use a 24" pilot with it. Are they reliable? Any mods? Any info at all about deployment bags? Would they at all help prevent a zipper, I am guessing they would because the cord is tait before the chute is let out? Are pilot chutes safe for deploying the chute?
