I'm looking for some advice on min poss freefall hight. I,ve been going 46" PC hand held, PC as open as poss, velcro half undone. I was once told that if I went any bigger on the PC it might actualy slow things down due to time for PC to inflate + lift, any comments? I'm looking at a road landing directly below object ( no manovering under canopy)

Thanks
