Hello to you all who read this ramble from me. Thanks in advance.
Looking at the picture ive posted here ! Ive put two black squares at the rear of my tail pocket.
Ive started to notice some line burns! Symetrical on both sides, ive tryed to take close up pictures of it but they are crap. Sorry. Im not sure where it comming from or why. Its only started to appear the last 5 or 6 jumps. The canopy is a 225 V and V troll. I only jump it slider off and Low 120 ft up to 240 ft as thats all ive got to jump around ere ! Usual static with the odd PCA when i want to go first. Ive read around the subject a bit but not heard of anything specificly like this. So guess i need some help from the community identifying the problem.
Troll is just 1 year old, done 50 jumps! Does not have the 5th control line. When i pack tail pocket sits on top as in the atair manual packing pictures. Top skin wrapped over and under. I must be getting a slack line or two whipping up ? Ive put a slightly thicker tail gate on. But same band and only two wraps. I was thinking a thicker tail gate would grip the line group a little more ? Dont know im stuck. And its giving me sleepless nights now whittling about buggering my canopy up if it continues.
Thanks for help ....

How do you get lines up there?
As I don't pack as "The Chuck", I usually place my clamps in that area.
Could it be the packingclamps?
And the picture doesn't show much, Do you have a bigger picture?

It does look like packingclampmarks.
Especially looking at pic 3.

What sort of clamps are you using? Are the tips worn through?

They are 6inch spring clamps. They not warn through.
They did have grippy groves in the tips.
But I've spent a couple hrs shaving that off with a craft knife and coated the tips in gaffa tape. There where no rough edges or sharp bits anyway. But I've done it anyway. Will keep extra close eyes on and see what happens. Thanks

have you considered the possibility of NOT using clamps?
my canopy only gets ass-cheek burns when I coil the lines...

I'm curious if you are sliding them along the fabric?
I tend to open the clamp completely, then move it into position, then close it. I have trouble conceptualizing how clamps could be creating friction-burn-like marks on the fabric.
For what it's worth, I have canopies with many hundreds of jumps packed with clamps (by myself and other people, some of them students) that are not showing any wear from the clamps.

I had a pair of clamps eat my canpoy once. They weren't my regular clamps and I stuck them too far onto the canopy so that the hinge of the clamp was all the way in against the fabric. Then they chomped that shit like a pair of scissors.

I think it's the extra tension the clamps make.
When you set the clamp it pulls the fabric apart at the very tip of the clamp.
