Hi Clint,
Aside from the Mixer bridle tuning which I'm sure you are aware of, there is this video from My Kite Life which goes into more detail.
Beyond that, send an email off to Flysurfer and ask for Armin or Benni to give you some help. Flysurfer is a very responsive company in terms of customer service and replying to emails and requests.
Regards,
DM
