I choose to do the pin with only 12 steps in the spin. The I selected the inner most loops at the bottom and scaled them to Z-0, to make the bottom flat enough. Also, since I’ve heard triangles are bad, I replaced the bottom surfact triangles with a Face - GridFill.
Here is the ‘topology’ of the pin I arrived at.
Now I realize others may have choosen more steps than 12 to get it smooth, but I rely in subsurf to fix that.
