Need Suggestions: Looking for XL Cross Frameset

So I am looking for an XL frameset.  I am just over 6'4" and currently ride a Specialized Roubaix XXL and an XL Niner EMD.  I would prefer carbon, i.e. new giant, crux or orbea but I just don't think that they are going to be big enough for me.  Really just need some suggestions as to what the other big guys are riding.  I saw somewhere on this board that someone had one of the big team Kona bikes but didn't ride it anymore.  If anyone can point me in their direction that would be helpful too. 

Thanks for the help.
