Mel I'm referring to small 300 lb line obviously stronger lines and different line types will get different life and that is stated If you read my whole post.
I did read your whole post. That was actually my reason for posting.
.... Your looking realistically at 75 to 150 jumps, some guys are getting more but when do you really cross the threshold?
When you start your post off with "here's the facts:" and this information follows, someone is going to take it for written value
Also, just for reference, there is a difference in line type and line tensile strength.
Type is how and what material the line is made of. Natural fiber, coated fiber, finished coating, etc... are just some examples
Tensile strength is usually listed as 80% of it's actual breaking strength in most manufacturer's worlds.
Just a note here. In PD's world it is whatever they name it to be so it could be the industry standard or not....
And I have a unbiased opinion about it because I don't manufacture lines and linesets.
By your previous statements, I believe you do have a biased opinion......
When guys on the PDFT are breaking over several lines on a opening it shows its something we all need to be aware of because if it can happen to someone with a lot of cost covered gear its more likely to happen to the everyday jumper pinching pennies
The PD boys are probably breaking the 200 Vectran on a regular basis.
Different story BTW...
As to the last part about the everyday jumper. This was my exact intent on my first reply to you. You were throwing jump numbers out for line set replacement.
My stance is more education and inspection of the lines in lieu of simply just replacing them at a certain number.
If you care to do the searches, you will find a lot of material on this site that I have put out over the years.
1 of the 1st things you learn in tree work is "When do you replace a rope? Before it breaks!"
We all know that skydivers are known for not listening to manufacturers. Don't take this canopy to terminal, don't take an RDS to terminal, an RDS is not made for everyday jumping, etc. There's always going to be someone who has to have the biggest swinging dick on the DZ who will break those rules and use whatever it is as an everyday canopy.
The difference with the competition linesets is that they can make problems down low, as we see here. If you have a problem deploying a canopy or with an RDS at terminal, the assumption is that you're also up above 2k (for most swoopers more like 3 or 4k), and you have time and a reserve to fall back on. Now that we have swooping that can introduce loads sufficient to snap lines that are past their prime, the old idea that 'if you can get it to open you're in the clear' goes right out the window.
When I was a poor young skydiver, I used to jump a line set until something broke. It was always on deployment, and then I would land it with a busted line and figure it out from there. Since those days, I stepped up to a Velo that I have no interest in landing with a broken line. So the new plan is that I get it relined every other winter, replacing the 'rope before it breaks'. Due to this, I've had no maintenance issues with the canopy in 1200+ jumps, and none of the cutaways or downtime that come with those issues. At the same time, I replace the risers on alternating winters, so everything is reasonably 'fresh' from the 3-rings up, and all for less than $1/jump.
I do it that way just to avoid downtime mid-season when I'm trying to spend my time jumping, not overnighting my canopy to PD and begging them to 'hurry up'. If you're jumping a competition line set, you need to have the same attitude to keep yourself out of the hospital. Come up with a plan the day you install the lines, and stick to it.

I was curious as to the #jumps you typically put on a line set, and the line type (material and weight). Can't quite figure it out from your post.
