Prior threads seem to agree
1. you need guy twing when running beamish to keep guy off shroud and better control of pole off forestay. and the guy needs to be inside lifeline {because the boat is so wide}
2. you need to run out side lifeline dead down wind to keep guy from putting a lot of pressure on stanchions and lifelines.
other than that individual crews work out what to do to help eliminate rolling or control of the lines when jibing.
Agree with 1 (or use a snatch block) but not 2. Never had a problem inside with the guy even dead down. Search the site with keyword 'twing' and you will get plenty of opinions. Mine is twings are a needless complication for W-L in typical weather conditions. Great for reaching or in high winds for example they might've helped
