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.

    I have to voice my appreciation for your kind-heartedness in support of people that should have help with this important concept. Your very own dedication to getting the solution around appears to be especially significant and have constantly allowed girls much like me to realize their pursuits. Your own important help signifies so much a person like me and even further to my fellow workers. Warm regards; from everyone of us.
