Psycho packing and end cell closure

[skymama 37]

I was taught to psycho pack my Sabre 2 170 over the weekend in the hopes that it would be easier for me to do and I might actually start packing for myself. It was a little easier, but I had end cell closure on both ends on every single pack job. I have experienced this before with a regular pro pack, but it only happened sporatically. Im loading it at a 1:1 ratio. My questions:
Could it be because I'm loading it too lightly?
Could it be because I was rolling the nose which caused me to have a longer snivel?
Does the psycho pack do something different to the end cells compared to the pro pack?

I'm psycho packing now as well, and I'm no longer getting end cell closure. I used to get that every jump with a pro pack, but now I'm not. I, also, roll the nose.

You roll the nose when you psycho pack?

I psycho pack my Safire, and don't roll the nose. No end-cell closure for me, and the openings are just about what I want (which is NOT a 900' snivel).

There is nothing more dangerous than breaking a basic safety rule and getting away with it. It removes fear of the consequences and builds false confidence. (tbrown)

On 4 of the pack jobs, we rolled the nose. I didn't do it on the last one, and I still had the end cell closure.

Are end cell closure really that big of a deal? I don't even see it as a problem myself, and it ussually meant my opening was fairly soft (not always though as I found on an out of trim Stiletto 97) Just a couple bumps on the rear risers and they are gone...

In reality the 2 methods of packing only get the parachute into the bag and how its going to unfold, once it hit the airstream stuff goes everywhere. The only difference I really see is the roll/not roll of the nose. Rolling (assuming symetric 4 and 4 or 3 and 3) just kinda gives the center cell that little extra jump on the rest of the canopy to open before the rest of the canopy, and ussually produces more on heading openings and a bit slow.

my $.25 (inflation what a bitch, to think it used to be a penny for your thoughts)

I've had them and it's not that big of a deal, but it should be taken care of before landing, which takes some time. Sometimes they just don't want to inflate, and they just add time to the opening sequence.

No they're not a huge deal, but remember, canopies aren't supposed to have closed cells. They're not "normal"...

No need to roll the nose on a psycho-pack... In fact, rolling the nose kinda defeats one of the advantages of psycho-packing. It makes it tougher to purge the air.

I have heard the opposite - that rolling the nose produces more off-heading openings. Can you elaborate with any data, or is this just based on your experience? And if so, what canopies?

I've been rolling the nose on my hornet when I psycho pack. Openings are usually on heading and I seldom have end closures. I'd say if your canopy snivels for a long time not to roll it. Mine opens too fast much of the time, so I roll the nose a lot.......Steve1

Data? nothing recorded or based on physics theory, 700 jumps on numerous canopies does give some empirical results. I have tried all the canopies below both with and without rolling and found all of them to open smoother with rolling the nose in the method described below. The only thing I dont bother with now is the Jedei cause its openings while more brisk by not rolling are still on heading so I shorten the pack job significantly. I have also seen the results when I have packed for other people then asked what they had in terms of openings.

Nitron, Safire, Stiletto, Jedei, Sabre, FX, Rage, and most importantly my Velocity (slows it down, removes much of the seek back and forth as its inflating)

Taking the entire nose and rolling it to the left or right will indeed lead to possible off heading openings. But a symetrical roll (assume 9 cell right now) take the first 4 cells roll them towards the center such that the roll is sitting next to the center cell (Not IN the center cell). Skip the center cell, take the final 4 cells roll it towards the center (we are talking like 2 180 rolls here) place it next to the center cell. Quarter the slider and pull the tail around.

I guess that I "pyscho pack" my stiletto 120. It is basically a straight pro pack with the exception that I turn the parachute around 180 degrees and very carefully throw it down. I then clean up the pack job, roll the nose and tail and turn it back over. I do not roll my parachute up like a sleeping bag, which is my understanding of the traditional "psycho pack". I cobra fold it as usual and bag it up. This is a very common pack job where I come from (UTAH, 5000' MSL). I know that the manufacturer recommends otherwise but I get very nice on heading, slow openings. I previously had a stiletto 135 that I pack ed the same way for 700 jumps.

I pyscho pack and don't roll the nose, dont have the slider sticking out and dont roll the tail on my xfire1 and the end cells are fine. Mind you the end cell closures dont happen when I propack either. There are two other pack variations that may help you (I'm assuming you are struggling to get a slippery canopy in the bag):

A mix of psycho and pro packing - propack and lay canopy on floor as per propack. Kneel on the canopy 6-8 inches up from the slider, grasp the pc bridle connector point, lift it and the canopy to your body, then roll the canopy down sleeping bag style toward your knees. Remove knees and place roll on "1st fold". You end up with a canopy that looks like teh number 2 from the side, only more curly at the top. Bag it. You may need a bridle extension for this.

Propack and lay on floor as above. Kneel halfway up the canopy and put the 2nd S fold in, bag that S fold then drive the 1st S fold into the bag afterwards.

Both of these ease packing sliPDery canopies

Psycho packing is named wrong, it should be called psycho bagging, its still a pro pack. But why change the way you pack whatever style you use, if you dont roll the nose on a pro-pack why would you do it with a psycho-pack/bag. Rolling the nose on an old saber is reccomended, but the saber2 opens so good there is never a need to do this, and you risk an extra long opening if you pack it this way.
Has your canopy, ever had end cell enclosure before? If it has then it might be underloaded.
End cell enclosure isnt a bad thing, you can just pull your risers or toggles and it will clear.
If you continue to have a problem, you can always bring it to the nice folks at pd and have them check it out, they have awesome customer service and will help you with any problem.
Good Luck.
