pro pack or psycho pack?

[jumper74 0]

I was taught to psycho pack. I tried to pro pack but find putting the canopy into the bag harder than when I roll the canopy up when I psycho pack. When I was taught to psycho pack I was showed to.. 1. Flake nose and hold between legs 2. Stow slider in center of canopy 3. Flake out tail of canopy keeping lines to center. 4. Then bring up tail..etc. etc. etc. I notice in pro packing you are taught to flake out the cells between lines a-b,b-c, and so forth. I was told that doesn't matter and has no effect on safety, opening, etc. My questions are this.. which pack job is better and does flaking out all the cells matter?

which pack job is better

Which ever one you prefer and gives you the most control getting the canopy into the bag.

Yes and no. You don't have to for good openings sometimes, but it helps keep the fabric uniform and helps prevent undo wear on the canopy from the fabric moving around and against the lines. Obviously it does help to prevent bizarre canopy malfunctions by having proper line control in the canopy's pack job.

Basically a pro-pack and a psycho pack is the same, except for the canopy bagging procedure. Before you lay the canopy on the ground they are the same.

Flat pack, psycho pack or pro-pack, who cares. Just pack consistently and get in the air.

I have a personal theory that psycho packing places an unnessasary twisting strain on the area near the d-bag on deployment.

As for flaking out the lines . . .

1) RTFM -- It's usually correct.
2) It distributes the bulk of the canopy in a predictable and even manner. Just shaking it out and doing the old burrito roll doesn't.

Could you explain your theory a little more? How is the twisting strain produced?

When I pack, the canopy ends up the same way round for both pro-pack and psycho-packs, its just one is rolled up and the other is folded. The lines exit the d-bag in the same place and are the same way around.

personal preference, they are both good. I can pack faster and cleaner with pro myself. I would say I do flake but, I have found my openings to be a bit more consistent when I do, and it only takes me about 25 seconds more to do. The only real reason to flake is to help the canopy material from wearing out too fast. I have seen people screw around and take forever on flaking and have malfunctions, and I pretty well trash pack and have had no malfunctions with a fully elliptical 150 loaded at nearly 1.7

don't try your bullshit with me!!!

Others allready answered most of your questions so I wont have to repeat those..

However I recommend you ask a rigger make you a psycho bridle extension if you are psycho packing.

What does the canopy manufacturer recommend?

My reality and yours are quite different.

The difference is where the forces are applied during deployment.

On a Psycho Pack job the center attachment to the D-bag is at the side. As it comes out of the bag, the lines are in line with the forces, but the center attachment point to the D-Bag is not; it's off to one side.

Take a strip of paper and S-fold it. As you take both ends of the strip and stretch it back out, you can see that there is no twisting motion imparted to it.

Take another strip and ROLL it up. Now, because the strip is rolled up, you have to hold on to the piece in the middle off to one side or the other. Stretch out the piece of paper and you'll see it twist.

My 2 cents...

Seems to me, PRO packing and Psycho packing are the same up until you lay the canopy down.

Originally, I learned to flat pack and later on (after 700ish jumps / pack-jobs) learned to PRO pack. Psycho packing was also going on at the same time, but after learning to PRO pack, getting the canopy on the ground, getting the air out, reducing the width and S-folding it into the bag was familiar at that point and not really an issue for me.

Having said that, psycho packing works too. Lots of folks do it. I always found the flipping and the rolling and the flipping back to be unnecessary for me as I already mastered another technique for controlling the canopy to get it into the bag.

To answer your specific questions... Which pack job is better and does flaking out the cells matter?

Well... which pack job is better seems to be a matter of choice... as in "some folks like Dodge and some folks like Fords", but they'll both get you there... as for does flaking out the cells matter... well... I'm a bit more of the opinion that flacking the cells is important, but, at the same time, I know a lot of folks that straighten out the nose, shake the canopy once or twice, quarter the slider, wrap the tail around and call it good... aka "a trash pack"

At the end of the day you're throwing a bag of nylon and string into the air at 120MPH and hoping for the best.

Everybody has their own way of doing it and that's cool. I think when most people are learning to pack they'll take a little piece from everybody who's shown them some stuff and make their own style. If the style you've learned gives you consistent, on-heading openisngs then stick with it. If not, then talk to some more people and evolve to another style.

Remember too that your rigger is packing your last chance, and if you've got a good one he's probably following a manual (or has already memorized it)

(kinda like a propack with a slightly modified psycho pack finish
