I use 2 swivels and hardly get line twist. This set up also lets the biting fish pull without feeling the weight in some cases.
Like this but lighter line

There is also sliding swivels with a plastic tube that might prevent line twist better but I have not tried it.

For trap rigs I started with trebles but unless you are using only huge macs you will end up killing a bunch of bycatch or shorts. They either swallow the treble or it's so difficult to remove that you handle them for much longer. Two circle hooks facing the opposite direction is what I started using.
