Not sure if this will help...my experience is with Dynaglide, but I use Speer No-Tangle for my Prussic loops. I can make one in a couple of minutes, utilizing a double fisherman's bend, and a 4 wrap Prussic sticks like glue on the DG. I haven't put a scale to it, but they haven't budged, in use.
It has always been my private conviction that any man who pits his intelligence against a fish and loses has it coming.

You can attribute some of the DG holding power to the vinyl coating. When whipped up in a whoopie, after loading, the bury is quite firm.
Try speer no tangle for your ridgeline, has alot of grip or bite. Your prussics are likely to fail before sliding on that stuff.
Thanks Opie! Blakes hitch worked for me (zing-it to zing-it)
