I ran 14/48 all season, until I discovered that I was faster using 'other' gearing. I ran 14/46 at Snett and 14/47 at Cadders. 14/46 for Jerez, but that was on slicks. Probably better on 14/47 on Diablos.
Of course that's with a standard engine, so it will probably be all different again next season!
May have to splash out on a 45 rear to make the most of the torque
