Rigging Hoops - Tying Polyethylene Knots

[bwana]

I am having trouble finding information on tying knots that won't slip using 1/4" polyethylene rope, such as sold by Promar.

Previously used braided loops for rigging with larger diameter poly ropes.

Need to switch to thinner rope to cut down on drag/weight and to rig some new gear. I don't want to tie the wrong knot, have it slip, and loose everything.

Any help would be appreciated.

Thanks in advance,
Mike
