Received some new NLO pQCD predictions from Werner incorporating DSS fragmentation functions.  Here's a comparison of these predictions to the old mocked up ones used in the SPIN 2006 preliminary result:




No really dramatic changes here.  The increased asymmetries might mean that g-g scattering is even more important than predicted originally.  Of course, this goes in the wrong direction if we're looking for better agreement with our Pythia.
