Just wanted to throw out an idea for the low jumpers.

I took an old PC and retro fitted the center line with 900 pound dacron and left small loop out of top cap.

When tied off the pc blows flat, PC is oriented in correct direction. Less snag potential (PC doesnt have to turn 180)
Can still use 2 tie offs or just one.

Ideally I would like to make a PC that could free fall or S/L. Dacron doesnt a good material for centerline. Thoughts?

I like the concept of the attachment point on top of the PC. Why does it need to be for freefall as well? With the way gear is so specialized any more a dedicated static line PC isn't too much more to ask for.

Sometimes ill freefall 200 sometimes I dont. Would like to have option at exit not at start of jump.

Why not just use the standard tape?

Would it hold up to repeated static lining?

You could make a tight loop (so it would be out of the way on free fall jumps) and then girth hitch a secondary loop that would actually attach to the static line. If the secondary loop got friction burned, you could just replace it. And you could take it off for the free fall jumps, too.

I'm having trouble understanding why you wouldn't have that option at exit. Taking the system off of the bridle wouldn't be particularly laborious would it?

Also, having the attachment point on the PC cap causes a longer fall, and more force on the static line, leaving the potential for premature breakage. Perhaps that's what you meant by "two tie offs" though?

What about a 5 foot bridle? Burble isn't really a problem when something as small as a body is only moving 20mph.

Why does one ever have a need for a pc staticlining? You dont trust your nutts. Sorry ,knots

The idea behind the PC is to have a 46/48 that you could freefall or static line. I have about 10 objects that depends on exit conditions what method I use. On a dedicated S/L jump I dont use PC.

If you are worried about the break cord breaking premature you arent setting up your jumps right.

I would definitely over size the center line to take the repeated loading. As you would know current PC construction is not built for that.
Also if you were planning to use it for free fall I would keep a close eye on the condition of the PC apex just in case some unforeseen circumstance lead to line burn or some shit that could lead to PC failure.

Wow..This is not a good Idea. Havent you heard of black death? Don't you at least want a chance IN CASE something black deathy happens? Seems like an unnecessary risk for a little PC management.

I'd never recommend a static line jump without a PC.

Maybe I'm just not bold enough...but I'd rather be old than bold.

What about a wingsuit jump?


Using a standard bridle and PC, you could attach a static line to the middle of the bridle. Then at exit you could remove the static line if your wanted to, or (not recommended) the PC if you wanted to. This setup would allow either option at exit, assuming you have pockets.


Apex has a video that shows the difference between setting the static line at the middle or the end of the bridle. There is about 40% more force exerted on the full length attachment (based on my quick calculations).

I love Todd but I was very annoyed when I saw this demonstration for the first time several years ago. A correctly used carry along static line with one piece of break cord is quite effective and im probably 0 for several hundred at dying while using it. The video makes it seem like there will be premature breakage virutally every time if you dont use a super complicated double setup. The force created by a weight dropped from that height is quite a bit different than the force required to open a properly packed base rig.

That being said, I solve the problem of not knowing for sure if im going to freefall by putting a 6 inch piece of break cord and my carry along in my pocket. I could probably tuck them into a mudflap if I wanted and keep them in the rig at all times. I think carry alongs are great to make sure what you are tying off to does not effect the breaking strength of the cord. The materials cost virutally nothing, and I have about 5 different ones at any given time that I use for various thickness objects.

So, I was just thinking some more about it, and I realized that the same acceleration that causes a decrease in break strength is also going to cause a decrease in the strength of the pin tension.

Relating it to something I know (I'm a physics major) it's just like an object having a gravitational effect on the earth the same way the earth has a gravitational effect on the object. It's also similar to a problem with a right angle pulley and two blocks. The tension goes both ways.

In summation: you're totally right.

Awesome so no help with centerline PC material ideas?



Know your knots.

PC bridle webbing for the apex line and top loop is the most obvious choice in terms of strength.

We have some of these in europe - with various materials - and some fancy systems that you can see here
