Destroyerator's Parachute and Deployment Bag

I received the TAC-9C parachute and deployment bag from Giant Leap Rocketry today. This will be the main parachute for the sustainer (the upper stage) of Destroyerator. I can't really tell how big it will be fully inflated but it's rated for 70 pounds descent weight and appears that it will be 15-18 feet across. The other parachute and bag in the pictures is from Positive Ascent, which is 7-8 feet across when inflated. This will likely be used as Destroyerator's booster parachute.
