My roll of graphite VX-42 seconds was delivered today. Almost 7 yards, I am sure I can come up with something to use it all up, but may be willing to sel a yard or two if someone out there is looking.
With respect to figuring out which material you have, the VX-07, 21, and 42 are all pretty different. In my package they included some swatches of their current stock. spreading them out, you can see that the weave of the top layer gives it away. The VX-07 has small square ripstip as well as the diamond pattern layer. The VX-21 is non ripstop pack cloth, and the VX-42 is pack cloth as well, but much heavier. The VX-51 is about the weight of heavy school backpack cordura.
The WX, TX, VF, .... swatches, that is just a downward spiral into temptation.
As for dealing directly with DP, service was great, packing was great, and turnaround was fast. I have a feeling I will be talking with Hale again soon.
