VERY complicated question and definitely a new thread.  No simple answer.
Answer depends on your rig, the cut and age of your sails and lots of
factors.

Over the years, I've added pre-bend to Touche's rig by tensioning the
forward lower shrouds (not possible with inline shrouds), added 5 inches to
the headstay, adjusted the turnbuckle on the roller furler, etc. in an
effort to optimize headsail and mainsail shaping.  The reconfigurations
came from years of sailing, racing, reading and discussions with sailmakers
and fellow racers.

Having said that, there are general suggestions that may apply.  If you
haven't read North U's book Racing Trim by Bill Gladstone, it's a good
start.  It covers rig tuning, sail shape and lots of topics pertinent to
your question.

I'll let others chime in for a while and see what's said.
