Ok, Thanks Grizz. Would a DL 1.1 be better than a single 1.9oz?
The piece I have diagrammed out would be one piece of amsteel. With the two "loose ends" attached to the soft shackles at the spreader bars. With that would bury length be important as the line isn't terminated in the splice, but rather passes through it.
Glad to hear about the UQ width, that will save me quite a bit of money, allowing me to purchase 1yrd of climashield and 2 yards of covering fabric.
