Difficult to say tbh.
In summer/autumn when the course is in prime condition and the greens are running very true, I would say that more birdies would result from faster greens (within reason). But in terms of Riviera in February, these greens are relatively bumpy anyway at this time of the year (not helped by being basically poa annua), so a truer roll should be achieved if the greens were slower, particularly in the afternoon.
