Estorils to polish or not to polish?

Hi i am new to this forum after just recently picking up a black 6n2 polo 1.0e open air for a run about, have already fitted remote central locking and a boot pop thanks to advice on this forum. I am now at stage where i need alloys on it and will be buying a 60mm lowering kit from philj soon. My dilemma is as follows, i have a set of 15" corrado estoril wheels which are needing a refurb due to paint bubbling and i dont know whether to refurb in silver as before, do them in white, polish them completely or polish the face and rim with black paint for the inset areas. Also have the option of 14" p slots as well which i have and could also do any of the above to. Any opinions would be welcome and pictures would be great.
