    Constrictor versus Whoopie sling

    Is less Amsteel required for the same length Constrictor versus a Whoopie sling?

    I know the whoopie forms one big loop while it appears the constrictor set up uses a single strand of rope with a constrictor at either end.

    Thanks.

    I suspect by "constrictor" you're referring to the UCR (utility constrictor rope). I never made the whoopie sling, I preferred the UCR ever since the idea was introduced by ZA206, back in June of this year. From what I see, a 15' whoopie can only extend 7.5 feet, simply because it is a loop. However, since we're generally dealing with Amsteel as the rope, the weight penalty is negligible. The proponents of the whoopie prefer it over the UCR because the whoopie puts tension on both ends of the "bury", while the UCR does so only on one end. With that said, I haven't had any slippage issues with the UCR. Frawg has suggested an idea using a hair elastic on the "distant" end, but I think I've gone way beyond your original question.

    Yes, there is less line in a UCR than a whoopie.

    I use 13' of line in a 6' whoopie sling.

    For a 6' UCR, there is roughly 9' of line.

    The UCR does not have a contrictor at either end. It had a fixed eye on one end of the main line and a fixed eye on one end of the constrictor. The fixed eyes are opposite one another and the constrictor slides anywhere along the main line.

    I am now building a prussick into the tail end of the constrictor on the UCR to act as a stopper knot.

    I initially switched to the UCR because of less Amsteel/weight. However, I also discovered another advantage (that I haven't seen discussed) ... ease of adjusting under load.

    I'll generally get my hammock set to what I think is fine and then load it up with UQ, TQ and other stuff I normally keep in the hammock or hang from the ridgeline. If I want to ADJUST the whoopie sling at that point, it's kind of tough. I need to UNLOAD one end of the constrictor, lifting one end of the hammock while lengthening/shortening the sling. That's easier said than done ... at least for me.

    However, with the UCR, I LOAD the other end of each constrictor by hanging a weighted silnyl bag (I store odds & ends from my BP in small bags). If I need to adjust the UCR, I just unattach the weighted bag, make the adjustment (noticeably easier) and reattach the weighted bag (important step).

    Im 265, 6'3 and the 7/64 has been fine.

    If you arent a gram weenie, and the 7/64 doesnt settle with you, then by all means go with 1/8.

    I made up a set in 7/64 for someone that weighs 400 pounds. I havent heard back from him yet. I told him if they fail I will replace them with 1/8.

    Sorry to re-open this thread

    One more thing I have found that I really like about the utility constricter is that the end is not a moving target. I generally put a short branch through the tree huggers and then throw a larks head around that with the UC, I tried this with the whoopie slings but with every adjustment I had to completely re-do the larks head because the loop moves. In the end I cut my WS and made it into a UC! I weigh just shy of 275 and have never had a problem with a 10 inch burry. Just my two cents.
