I came across this video that shows a Petzl team carrying out some pretty thorough tests on screw and Abalokov ice anchors. It’s instructive. Which do you believe to be stronger; Abalakov thread anchors or a “good old” modern ice screw? The biggest problem these guys had was in finding a patch of consistent quality ice to enable a reasonable degree of “fair testing” to give their results some meaning.
