Packing Problem (Line Twists) Solved

Recommended Posts

I would like to thank Louis French for his time to help me figure out my packing problem. I was having line twists on almost every jump. I spoke to a lot of people and asked a lot of questions and could not figure it out. Louis gave me some tips and made some suggestions after watching me pack and I’ve jumped my pack jobs several times with consistent straight on heading openings and no line twists since.

A definite improvement and complete turn around. Thank you Louis!

I can't tell you the exact cause and I think it was not just one thing, but one thing that Louis suggested which I was not aware that I was doing was to make sure that the lines are stowed straight. He noticed a twist in the line immediately after coming out of the bag and into the first stow. It's entirely possible for the lines to get twisted gradually as you are stowing so this may be one thing for some people to be aware of and make sure they are not doing.

If I didn't notice it while stowing that time I'm sure it could have happened before without me noticing.

It's nice getting good on heading openings again.

I've been having linetwists pretty regularly too. I noticed that during deployment the twists were already there during the first part of deployment sequence as the canopy was still in the dbag. The canopy was snivelling and opening on heading even with a twist or two.
What I started doing now is to pack the dbag straight down - with the line stows towards the back of the container and not the bottom of container. This way the dbag lifts off straight out without having to rotate. This packing technique is even mentioned in the container manual. 30 jumps and not a linetwist since! Btw, my container is a wings ext w8-2

I have a wings w17 with a Triathalon 190 and have tried to position the d-bag as you mentioned (with the bridle towards the flaps and found that the d-bag shape was too rectangular and 'tall' in this orientation. YMMV.

My dbag seems to have a fairly square cross-sectional profile. It probably also helps that it's a 97 sq.f canopy going in the dbag. Or maybe it's because it's an EXT container. Anyways, it fits nicely into it.

At a point I was getting frustrated at people telling me that my linetwists were being caused by body position. I spent an entire 13,500 jump doing practise pulls and found that they were indeed changing my heading. So I fixed that and found it greatly reduced the linetwists. Finally leaving a little more extra line (about 20") from the last stow made another difference. While I don't have experience enough to give advice I can say that sometimes linetwist is caused by more than one thing.

Yea it was. I just can't tell you for sure what else it was. I just know that could have been one major contribution to the problem. One thing that suggested was to replace all of my rubber bands and I did that.

I've been told by different people that A.) You should stow less line into the rubber band and B.) You should stow more. Stowing more (about 2-2.5"?) seems to work well for me so I'm sticking with that.

I also got a tip from another person on how to route the lines in the container. Something I was not at all sure of how to do right. I've been told by several people when placing the bag on top of the lines that you can press down and twist the bag a bit and then others have said to just leave the bridle hole pointing straight up instead of towards the front. I've never been comfortable with turning the bag once it's in the container, because I felt like I was sliding the bag against the lines and causing them to shift. There are so many bad scenarios going through my head when I did that.

You get so many different opinions from different people. It gets confusing.
