I don't know if this has been tried or if it is even an issue. I realize pilot chutes are the cause of offheadings more often then not. Out of the hundreds (low hundreds) of off heading BASE deployments I've now seen it very much appears that the canopy is turning right as it leaves the pack tray. The pilot chute bridle can also appear to be visibly wound up slightly at this point too. I was curious if the pilot chute is providing some torque (spinning) to cause this. It seems like it would be more apparent on the multi as it has more area to torque with. So if this is the case (and someone explain why it wouldn't be) then wouldn't a PC that can spin freely be more effective?

Just a thought.
