Go for whatever wheels you want.
The TD 1.2's are very nice, always a good choice.
I have 18's myself and you have to know the roads you are on very well to avoid dangerous potholes. I have 18's and lowered so the ride is hard but not bad. Nothing changed because of the change either performance wise
Up to yourself but the TD 1.2s are nice
but so are the OZ range.
Too many to choose from to be honest lol
