Spigot Rings - Plastic or Metal?

[T6180]

I need to purchase some spigot rings for my new alloys....i need to go from 65.1 to 72.6 which I believe are BMW/Range Rover fitment. My question is do I buy plastic poly or Metal and are there any brand/companies people can recommend?

Have used plastic before with no problems.

In my experience spigot rings, where needed, have been plastic. Again, no problems experienced.
I can see the potential for problems with metal items - corrosion for one.
