Cheers thanks guys just wanted to make sure there isn't another option I 
could easily set to false.

This way it only runs the 2nd time.  The only problems I can see is if the first default plot is needed to get some parameters for setting up the pdf/eps devices, and if you want to include the code (not just the plot) in the output then it will have the extra test.
