The beads on both of my whoopeis broke so I replaced each of them with a tiny S-biner - handy to hang stuff from too.

Somewhere on a thread somebody mentioned putting a 1.5" piece of whatever your using for your whoopie burried where the bead would go. I cut a 1/2" taper on either end of a 2" piece of the 1/8" amsteel and burried it and it works like a dream. PS thanks Opie for all you did with the amsteel.
i just made a pair of toggles and they are tied to my whoopies with an 8" length of shock cord which would act like a bead, and i cant drop/lose my toggles.
Like this? The adjustable bury doesn't start as close as it looks in the picture, it starts about 5" up from that.
that's a cool tail bead. i don't use a bead on the tail, although, i have considered tying a knot there. i tie my toggle attachment cord up in the adjustable loop to prevent accidentally pulling the loop into the bury. sorry no pix.
Ok We got Pics
first one shows the burried piece
Second shows whoopie pulled tight
Third shows length
fourth shows whole thing with pen indicating burried piece
Nice zirk! I like that, simple and effective.
Like I said I saw it somewhere on another thread and if I could find it I would give credit where it is due but right now I'm clueless as to where it came from
Samson says whoopies degrade line strength by 40%, slightly better than some knots and much better than some.
"AmSteel® and AmSteel®-Blue Whoopie Slings have a break strength of 60% of the published average ROPE break strength."
Link to that quote.
I use 50% as a rule of thumb for both knots and whoopies.
No matter what the "strength" rating is, you need to remember those are all "static" ratings, which are laboratory-controlled, and thus unrealistic. In actual use, it is the "dynamic" effective weights that are critical and that cause lines to break. It's easy for dynamic motion to effectively double your weight (or worse). Think of how some people plop into their favorite chair. 200lbs suddenly becomes 400 lbs for a few seconds.
Additionally, something similar happens with regard to the geometry and physics of hangs. In the laboratory tests, besides being static tested, the lines are tested exactly vertically. However, hammocks are hung close to horizontal. That also can double your effective weight (or worse). Now a 400 lb effective dynamic weight becomes an 800 lb weight effectively.
Suddenly a 2,000 lb rated line has very little margin of safety. It's reduced to 1,000 lbs by knots and whoopies and biners, etc., and the hammock hanger sitting down hard or tossing in his sleep places 800 lbs of force on the rigging, with his backbone right above a root or rock. Hmmmm. Not for me.
That's why professional riggers often use a rule of thumb of 10-to-1 when human safety is involved. YMMV.
