That PDF is from 2003. The document original posted in this thread is from April 2009.

Is there one available from, say, 2006 or so? That way we could check if the front hubs from that time frame - like the HB-6600 - were approved for radial lacing. Note that in the 2003 document, the HB-6500 is approved for radial lacing, and in the 2009 document the HB-6700 is approved.
