Direct Loading of Dyneema Slings 14-Apr-2010 At 10:57:15 AM davepalethorpe

>>so falling a lesser distance does reduce the impact force even if they are both fall factors of 1??>>

Surely this is not too suprising. From my understanding peak impact forces are effected by the duration of the deceleration. Eg stretchy rope equals longer time to dissapate energy over, resulting in a lower peak force. More rope, more stretch which is why a factor one fall onto rope generates a similar peak impact force whatever the distance. With a direct fall onto a dynema sling that has near zero elasticity no matter what length it is(?) the main factor on peak force is how quickly you are travelling (ie height you fell from).

Think the long and the short of this discussion is don't go wandering around on belay with yards of slack dynema and all will be good.
