I'd 'go scenic' and avoid the A roads like the A30 personally, but it depends on what you're after.
If you're going FG/SS then quite a low gear is recommended for the coastal stuff coming out of coves can be < 20%. The 2nd route less of a problem.
Don't forget to check the King Harry ferry is running for the 2nd route (it should be at this time of year).
If you get time for a 3rd ride try and get down to the Helford Passage and the Ferry Boat Inn. Every cove down there is stunning.
Other things...
The Lost Gardens of Heligan is a not too far away and (I think) much more interesting than the Eden Project.
Pick the right evening and the Minack Theatre is just about the best hot date venue ever so keep that in mind.
