Depends on the rocket. On rockets with HED or a really heavy nosecone where it falls like a home sick brick and drags the fin can behind it, I use a drogue to slow it down and flatten out the fall between the cone and the fin can. On others, I tend to run long shock cords and then all just seem to naturally fall flat - rockets from 3lbs to 60lbs. The length of the fin can along with the drag of the fins vs. the length of the payload section all plays a part as well but typically for me, HED rockets have all benefitted from a drogue. Others that I have flown both with drogue and without, i have noticed little difference besides a slower decent rate which I didnt really need.
