We did some drop tests on gear the other day and at the end of it all i can say is that our gear(tree climbing gear) is very very strong!We were videoing our DBTree rope savers with 80-100kg weights being dropped from 1m,2m,3,4m and seeing what would happen/break. nothing broke at all. This is one of the tests-http://www.youtube.com/watch?v=IiiodscSlS4 and theres others there too
