Spinergy XAERO lite or Neuvation R28 Aero 4
 

Which ones should I get, the Neuvation ones are cheeper and i have heard mixed reviews, does anyone have anything good to say about either and why I should get one or the other, the weight is about the same +30g for the R28's. Also if there are better rims around the same weight in the same price range also please say. These will be going on my Orbea Opal with sram cassette....
