Both me and a friend had easton ea70 bars and went to ec70, the ec70 were a much better bar even the weight difference seemed to help handling, not sure how but it was a noticeable difference all round. Moved to the havens and they are another improvement, have also paired them with the haven stem which is also excellent and only £65 from merlin bargain once I sell my Thomson for £40! Also consider the haven carbon bar has a lifetime warrenty and the alloy ones are only 5 years.
