Do you mean WBT Nextgen or Eichmann Cable Pod binding posts? I find it difficult to imagine that the WBT could be overcranked under any condition. I will say that the sort of pressure I have seen some people apply to Eichmann binding posts to be frankly way over the top. It's not a he-man competition with post wrenches! Furthermore that completely defeats the point of the superior-sounding Eichmann design. I personally find the tactile feedback of the Eichmann posts to be excellent, and stop when I encounter resistance. Never had a broken Eichmann post, ever.
A pet peeve, if I may: the people who use a pipe wrench to "attach" cables to amps/speakers probably have no idea how fragile the wire on the other side is and how tenuously (just a dab of solder) it is attached to the post.
