I just converted this morning over to whoopie slings and I am running into some issues with how Hennessey sets their hammocks up.

First, my setup for the conversion is a 12 inch "dog bone" of amsteel to secure the end of the hammock, to a Dutch biner, then to a 6 foot whoopie sling. The issue I'm having is in the prussik knots that secure the tarp to the suspension. One, they fall on the constrictor part of the hammock making adjustments a pain. Two, the prussik no longer bites into the slick Amsteel like it did on the previous line. Now it just slides easily back and forth on the sling without holding tension on the tarp.

Do you have to use a different type of cordage for your prussiks when using Amsteel?
