Allow me to clarify, I guide climbing trips for a University, we take 10 or so students at a time to crags for single pitch top roping and sport climbing. I once heard that it is a better ethic to set up a top rope on gear/trees when having rookies (who fall a lot on TR) on the line. Thus extending the life of the anchors, though very time consuming. Looking for opinions (I feel that using our own draws is fine, and that TR falls only weight the anchor, and as not a shock load are hardly detrimental). There are no certifications for guiding I hold beyond WFR and a BA in ORec and all other guiding I have done has been for hikes and backpacks.
