Oh ok I hear you. My preference is to spiral turn/circle my rope prey to bleed off the E and bait him in but your way would work well too.
Prefare the spiral myself, keeps you out of guns and con pulling lead and burning more E. More importantly it reduces the distance and time you have to drop and is more likely to result in you catching the con in a stall for an easy big profile shot and kill. The standard rope requires distance to avoid an easy static shot even at 800 a cannon bird could get a lucky spray, by the time you get over and down the con is usually well on his way down as well.
