Answer:
There are currently (9.30pm 14/11/13) no clubs in the top Vifa rank #100 without Premium.
There is one culb in the top #200 and one more in the top #300 (but he sold up as his previous subscription ended and is dropping like a stone with a team of kids.)
There are only 6 clubs (- those two included) in the top #500.
There are a total (those 6 included) of 72 clubs in the top #1000 without Premium.
Depending upon what your version of "doing well" is... - it would appear that to be successful, in terms of #Vifa ranking at least, you probably do need Premium to get to the top.
