Crevasse rescue - 2:1 drop loop

Hi,

One quick question about the 2:1 drop loop system, the rope your pulling on has a prussik on it. Should that prussik be anchored to a figure 8 on a bight to the other side of the rope you're pulling on, or right on to the anchor? I've seen it done both ways, and not really sure if theres any positives or negatives to either. Thanks!

Either way seems correct to me. If you put it to the anchor then there is one less knot to untie at the end. But if you don't have enough rope to reach the anchor then there is no problem with creating a closed loop by clipping into an 8 on a bight.
