Welcome Hoge.
The chrome 10 spokes are the easiest to clean but they can have the corrosion that causes the cracks.
The Mark VIII original wheel choices are the 10 or 20 spoke directionals in chrome or painted, the chrome octastars, or the aluminum lacey spokes (often called snowflakes).
You should be able to see examples of each type in the Members Rides section.
If you see my cars there, you'll see every type except the painted directionals, although I do have 2 painted 20 spokes in my collection.
