After AngrySparrow reported on his experience with this ebay samthane coated dyneema, I figured that for $45.00/600', I'd give it a try also.
Well it arrived today. I ordered on the afternoon of the 22cd. 2 day service/delivery. He is prompt.
I have the BackPackingLight AirCore Plus
dyneema cord. $40.00 for 50'.
This ebay stuff is indistinguishable from the AirCore stuff.
I have done some limited testing with knots, bowline, figure 8, Prussik using dacron guyline cord for the Prussik, Icicle hitch, Blake's hitch, sheet bend, double sheet bend, adjustable hitch, lineman hitch. They all held very well. I liked the performance better than the BPL AirCore Plus. This stuff is about the same stiffness as the AirCore Plus, i.e., not very stiff at all.
I'm inclined to believe the ebay rating on breaking strength plus or minus 100 lbs. I'd say it's in that range. BPL rates their AirCore Plus at 1109 lbs. I can easily believe this stuff is about the same.
I'm still intrigued by the APS 1.75 mm "twine". I go through 50' lengths of guyline cord too fast. I have so far purchased 3 or 4 of the BPL 50' lengths of their guy line cord. I like the way it handles and I bet the APS "twine" would be very similar after handling this stuff. 50' of the BPL guyline cord is $25.00. The APS stuff on a 600' roll would run less than half that, $10.00 and change. I like the dacron guyline cord also, but have found that knots "set" in the stuff. Tie a sheet bend and leave it for 24 hours or so, then untie it and the dacron cord retains the sheet bend shape. Makes it very difficult to tie another knot, I'm always fighting the cord trying to get the shape of the previous knot out of the cord. Don't have that problem with the dyneema stuff I've used.
