I've used the Easton ally risers and found that they transmitted a little trail buzz on certain surfaces and made my fingers go a bit tingly. The Easton carbon Monkeylites cured that. Not too keen on Easton's latest batch of carbon risers though, the logo looks sh1te (IMO) and you can't see the carbon weave any more so looks a bit 'plasticy' (my mate just bought some and wasn't too chuffed about that).
