Optimum effectiveness of the parachute, use shroud lines 1.5 times the diameter of the chute....A hole in the top of the parachute helps to keep the rocket from spinning on it's way down (trapped air doesn't "spill" out the side but instead goes thru the "spill hole". How heavy is the rocket (with empty motor casings)? A spill hole will speed the descent.
