I think the Easten Havoc wheel is is a better comparison to the Crossmax SX since I'm guessing you probably need a 20mm front hub as well as the 12mm rear (Haven is 15/9mm FR/RR)
As far as weights, they are probably comparable. I say comparable because I have the Crossmax SX wheelset and Mavic claims they are 1750g but mine weigh in at a touch over 1800g. Easton claims the 2011 Havocs are 1800g.
As far as I know, there are no changes to the Crossmax SX wheels from 2009 to 2011. However, I would recommend you steer clear of the 2008 models as I have heard too many issues with rear freehub issues that were supposedly cleared up in 2009.
Another point to note, the 2009 Crossmax SX hub has 48 points of engagement, whereas the previous were 24. I also believe that Easton has 24 points of engagement so be sure to factor this into your decision as well.
All that said, my next wheelset will be a custom build with Hadley hubs laced up to Stan's Flow rims. After the downtime and expense of replacing a busted Crossmax spoke, I'm steering clear of the proprietary stuff. Hadley's also a super durable and adaptable hub with better engagement. Hope this helps!
