What are people's opinions this
I am still closing my rig the "old way" as I learned that way. Is this an issue in terms of safety or is either ok

You could end up with a pierced bridle by closing the "old" way.

You could end up with a bag lock if for some reason you were in a head up position on deployment.

Can you explain? I don't see how it can happen.

The whole video talks about pilot chute in tow, not bag locks. You owe 10 minutes of my life TongueWink

So the Vortex is changing from laying the bridle 'down from top to bottom, across the side flap', to the 'up from the bottom' method, to reduce the chance of the pin piercing the bridle and locking the container.

What I find interesting is that this is the first time I recall seeing a company completely change their system, instead of just making the new method an option while retaining the old method. I don't think anyone has proved that the top-to-bottom method necessarily has a risk of locking up, unless packed with poor pin and bridle placement. Nevertheless, the mechanisms of pin lock are still fairly hard to duplicate.

Is the bridle pierced during opening or due to wear over time and poor gear maintainence?

Guess I got some packing practise to do this evening. Can't wait for people to tell me how I am using the wrong method when i am next at the DZ :p

LaughLaugh Coming up from the bottom IS the old way. There's nothing new about it at all. I've gone back to it and I like it. Mechanically, can you think of anything wrong with it?

When a lot of this stuff was invented, we looked at it very hard to see what worked, what wouldn't work and where things could go wrong. There were a lot of hard earned lessons. Think about the mechanics of it all. Smile

The "original" way or the "new" way are not wrong. But sometimes people get creative Angelic

If that were true, then there would be a high potential for a PCIT doing it the "old" way if you were head low.
As long as there is an inch or two of slack in the bridal between the pin and the bag this will not be a problem. This is not NEW. This has always been done with CRW canopies with retractable pilot chutes.

New way doesn't seem to have much slack.

You don't need slack if the bridle is coming out from the bottom. You do need slack if the bridle is coming out of the top.

That's why the Velcro tab and the slack in the bridle
