Re: [Butters] cut aways on BASE gear
If the links allow too much freedom of movement for the rings, here's what can happen (assuming that the loop failed or you're not using it): the smallest ring gets half through the medium ring, the medium gets half through the large ring. The 3-ring system is based on the leverage principle: say, 1/10th of the force on the large ring gets transmitted to the medium ring, and 1/10th of that is transmitted to the small ring, and 1/10th of that is transmitted to the loop, so 5lbs force on loop/cable can hold 5000lbs load on risers (numbers are for illustration only). When the rings can partially get through each other, that leverage factor is greatly reduced, say, it's now 2*2*2 = only 8. The result can be catastrophic.
