Not so much twists but yes I'd always advocate for vote to save over vote to evict, and for minimum 3 people up for eviction as over the years there were some great housemates lost simply because of being head-to-head with another great housemate.
I think there should be OCCASIONAL votes to evict, and occasional head-to-heads, but those should be the exception and for specific reasons.
What absolutely MUST be avoided is the Ch5 era nonsense where they went through a phase of only deciding whether it was Vote to Evict or Vote to Save after they knew the nominations results, so that production could manipulate the likely result
