Kev's damaged are often better than a lot of folks 2nds.
If you're up for stitching the slashes, it's easy stuff to sew.
The chutes come odd shapes too. Sometimes it's actually better to cut out a couple of rows of panels to make them flatter, and if you get lucky the bits you remove will work for repairing damaged panels.
It's worth trying for one with it's lines still attached. It cost me the price of a drum of paracord to replace the ones that had been cut off my chute. You really need four metres per line if you're going to put the chute above head height and tether it securely. 20 or 25 lines at four metres is pretty much a drum full of cord.
If Kev still says the chutes aren't worth the trouble though, I'd take him at his word; he knows his stock
