In reply to steveb2006:
I don't pretend to understand the technicalities and I don't own any Totems, mainly because I have a fairly new set of Dragons, but I have used them on a shared rack. I have to say that I found them very reassuring. They seemed to sit very solidy in cracks and pockets and tbh after using them I rather regretted getting my shiny new Dragons. That said, happily I did not test them in anger but my impression of them was very favorable
