Marvin,
Check out my original posting for the size and shape.
I like the rod style because they won't slip off and grab together like the flat style does. As to strength, I just bought what was in that size. The Neodymium Rare Earth magnets all seem to be very strong. So strong that when the poles are together it is quite a feat to pull them apart.
