20G Choke size for Skeet?

[GeordieTrapper]

I have just purchased a 20G 2005 Browning MK70 to use for skeet. I understand that 20G needs less choke than a 12G.

What chokes would members recommend, Super Cylinder, True Cylinder or Skeet, or a mixture? This is only for skeet

Any of those 3 will be fine
