Looking to keep them in good condition for a few years, I'd go for single spoked like on the type shown, but I have a problem with 7 spoke wheels on a car with 5 wheel fixing bolts! Having said that, I have got used to my 19" 7 twin spokes I use in summer, a proper pain in the bum to clean though! I use 18" 5 single spoke wheels in winter, very easy to keep clean.
Don't use Lkperformance! Took £1800 from me and the wheels weren't even in stock although advertised on their website and would never be in stock! Refund only after two weeks and numerous emails! Not even an apology! Avoid!
