The U Saver is the Pulley Saver I assume. Is that right?
I'm going to get a lock jack soon enough, and I want to have my retrievable tie in system all dialed in when I get it. I really like the speed and viable use of the DRT rope on a pulley and clutching mechanism (I hope that makes sense). The prussic on a DRT over the branch is too slow IMO.
What's your choice of clutching mechanism, or are you using hitches? I'm still in the air about the Lock Jack vs. Spider Jack. I'm very impressed with how demonstrators use the spider jack, but the spider jack has the wooden lever that can stab you in an accident.
If this is all JP to you, let me know. I know there's level of skill in the buzzer group that I might never reach. I appreciate the knowledge.
