The Archetype cable cutter with a small drogue on the shock cord to keep the nose cone above the booster during descent has worked great for my LOC 3.90 V2 with nose cone AV bay with one exception... the main deployment times are long. In two flights, it took 8 and 15 seconds for the burrito to open. This is the setup at apogee drogue deployment.

In the flight with the 15 s deployment, the main opened at 100 feet. Better late than never, but :y: !

This is a known issue with this type of recovery because it takes time for the burrito (bundle holding the main chute) to catch air and unfold after the cable is cut. Using a drogue on the shock cord likely makes this worse by slowing the descent.
Some good feedback from other forum members led me to the conclusion that some means of attaching the drogue to help open the bundle was needed for this recovery system to be reliable. First 8 seconds, then 15 seconds means the deployment time is not predictable. Sooner or later, the main chute is not going to open on time.
