Hi,

I discussed with two jumpers that are jumping on ZP canopies for at least 150 jumps, and what they say is that the fabric seems to stay as solid/consistent/non-porosity as at the first day, so they are very glad of it.

Without considering the added weight, I was wondering if the same kind (ZP vs F111) of improvement did exist for other parts of the gear :
- the lines that gets scratched (I don't know the right term) by the slider : does another material could be used to make them stronger?
- the 'fabric' used for the container
- the different velcros
- well ok, I don't have many other ideas of parts getting more hurted as the canopy and the lines, but I could speak about the slider, the bridle, the legs and chest straps, aso...

are these jumpers useing full ZP BASE canopies? or useing partial ZP topskin Canopies? personaly, i hve not jumped a full ZP canopy for BASE, but i jump a blackjack with ZP foreskin. F111 stretches slightly more than ZP, and that makes it stronger for BASE. the fabric around the line atatchment point stretches, equalizing the force and distributing it throughout the cell. BASE openings are fast and hard as you know, and ZP could over stretch, and tear. Im just speaking on opinion, i have not tested anything.
I would like to jump full ZP canopies at potato to see how they do. bring a specter 220.

I've always been under the impression/understanding that the only reason for not using ZP is that full ZP would slow the inflation more than is preferable.

when manufacturers make stuff they make choices regarding:
- materials
- cost
- strength
- durability
- reliabilty
- availability
- ease of use
etc.

one problem with making things strong and stretch resistant is that the various forces get absorbed by your BODY, not your RIG.

that's a good reason to prefer Dacron lines to anything else...

Yes duck tape

- the 'fabric' used for the container

duck tape

- the different velcros

duck tape

duck tape

And nowadays it comes in colors other than gray.

When I read this I instantly think of automobiles. Originally the frame and body were made to resist bending and breaking, but soon people realized that all the force of a sudden stop has to go somewhere. They realized that making things so they absorb this energy saves some people from at the very least whip lash.

While making things stronger may have some very positive impacts, the finality is that, no matter what "shit wears out."
