South Tyrol- Things new to me.

Threading directly thru pitons, bolt hangers and other "Questionable" anchors to save carabiners.
Tying the loop closed with an overhand knot rather than a water knot or double Fishermans. Thought this would slip and roll under tension. Still not sold on this part.
Girth hitching the carabiner with several strands, rather than tying a big overhand knot on a bite. I alway thought this would slip too. What I like about it, is it saves cord otherwise used in the knot. A single runner can reach two bolts 200 centimeters apart. A double runner three, etc. You can get more done with fewer carabiners and runners. Nice for old men carrying gear into the backcountry. The girth hitch is easy to tie and untie with gloves on too.

I also like how they describe the two types of belay anchor systems.
For two large solid bolts - connect them in SERIES.
For two or more traditional "questionable" anchors (pitons, cams,stoppers etc.) connect them WEIGHT DISTRIBUTED.

Simpler than SERENE or ERNEST acronyms. I can't begin to remember what those stand for.
