Outdoor Wheels

So I am going to try and attempt the roller marathon thingy at Goodwood - does anyone who skated last year have any wheel recommendations?
Hermaphroditie skated it on the black radar tuners, which I have got, but apparently they were 'a bit vibratey' so I'm considering buying some outdoor ones for this event.

I used some of the radar energy ones from everglides. They were okay, but everglides seem to have sold out. I duno if I'm gona brave the marathon again this year - so if not I'll loan my wheels!
