Anyone know the difference between these colonial chokes?

12 GAUGE COLONIAL SUPER STEEL TRUE TUBES
(.795 x 44)

12 GAUGE COLONIAL SUPER STEEL
THIN WALL TUBES (.774 x 44)

12 GAUGE COLONIAL INVISIBLE SUPER STEEL TUBES
(.812 x 32)

12 GAUGE COLONIAL LONG INVISIBLE SUPER STEEL TUBES

I am just looking for a basic choke. I think the first one will do. There is a full like this one installed currently.
