I cut the corners and make it in to a 12 sided parachute.
Much stronger and a slower more stable decent.

K Tesh, understood and agreed.
A and C are less likely to cause twists in my opinion. If you use B the "middle" line can easily create an unsymmetrical canopy shape that will result in the canopy spinning or twisting up the lines, which is exasperated in a smaller size canopy.
Mathematical proof please!Actually, if you make all three lines the same length, B will have all the same length shrouds, just like A & C. There will be no asymmetrical shape unless the canopy is cut out uneven. If you cut out a 12" hexagon that is a perfect hexagon and all three shroud lines are 24" long, all six shrouds will end up 12" long.
Mathematical proof please!
Remember, shrouldines and barrel swivel loops have a thickness greater than 0. Thus the lengths will be less than 12, maybe a different amount less for the middle one, maybe not.
I don't know, but I think it has to do with how Estes makes the middle line longer. So I'm assuming people thought of a reason and 'because it should be' worked for them. The reason could be valid- or not.Why would the middle one be any less then the others? You use the same length to attach each end and the same amount goes into the loop for the swivel. The final shrouds lengths from the swivel loop to the chute material will be the same for all six shrouds. If you use 24" long lines, of course they won't have a final length of 12", but they will all be the same.

With a hexagonal chute, the distance across the chute is the same as double the distance of two edges. So going across the chute with one of the lines works out.
With an octagonal chute, that relationship doesn't exist, so the shroud line going across the chute needs to be longer. Depending on the size of the chute, you may not notice and the chute may be pulled in a little bit.
I should have mentioned that I was talking about arrangement "B" where one of the shroud lines goes across the canopy. It works out just fine as a hex with all lines being the same length, but the length of the line that goes across the canopy has to be longer with an octo.
