I have to admit that today while way up in a big oak doing pruning, dd wood and cutbacks, 2 different times I had both beaners at both attachment points cantilevered which was the reason the
zz was deep sixed. I am very aware of my gear and did not sit into the weight however I can see how someone would and I believe an instructor was bouncing into it when it broke.
I will probably ask to trade in my old ZZ once my new one arrives this week.

You are a tough old dude, Dave. Be careful, I have not climbed (production) in 11 years. I have 6 seasoned climber's and 2 we are training, I have 6 groundies and 1 or 2 that might want to train to climb also.
I think they should (and will) learn old school first and progress as they learn. I find that some are just natural's and some are wanna-be's by starting them old school and then buddy up to one of our seasoned guy's and go from there.
