Nice tires.
What kind of course is it? Are there other factors related to the course that should be considered? Do you know anything about the road surface?
You're going to get a thousand opinions about the right pressure and what is faster so forget finding a definitive answer.
Here's mine:
Continental sew-ups (sew-ups...that no longer applies here...I digress) generally like to run at a higher pressure than other brands. I base this on personal experience, conversations with other users and with Continental itself. I have no data to back up my assertion.
I have not ridden these tires. I am very familiar with the compounding (I ride the GP4000s clinchers) but I am curious to know how the fusing of the tube to the casing affects the sidewall. Perhaps someone who has can offer you some real world information about handling characteristics. Combine this with the characteristics of the course and you should be able to ballpark pressure from there.
The rest is personal preference and Voodoo.
