Teen arboriculture program climb

I recently led a rec climb for a teen arboriculture program called "Branching Out". They've been climbing in more old-school arborist style harnesses and using body-thrust technique so it was fun to put them in more comfortable New Tribe harnesses and show them some efficient climbing techniques that were less strenuous.

Looks like a fun climb.

So here's what I want to know. Did they adopt the easier methods or did they revert to the familiar body thrust?
