Partial smoothshaded cheesewheel (leftmost one) looks best IMHO. You should do the actual brick of the cheesewheel as quarter and eighth bricks - like wedges set up in such a way as to be able to be placed into the cheesewheel.
When you release those you should include the actual models and maybe item icons of them (with and without the semitransparent circle background) in the zip for modders to use in their projects.
Oh, and might I suggest smoothshading the vertical strips of the apple? I'm not sure how it'd look but I'd like to see
