At 63kg I rode 23mm tyres at 95psi front and 100psi rear; 5-10 psi less in very slippery conditions; equal pressures for hillclimbs; maybe 100f/105r for TTing & RRing on reasonable roads. Clinchers, BTW.
At 70kg, I've generally gone to 98psi front and 103psi rear, or thereabouts, for general riding; and 110psi front and rear for Herne Hill.
Only had a snakebite puncture once, at 110psi, and I think it would've happened with <120psi due to the 'emergency' nature of the impact.
I have been known to ride very fast, but what mattered more to me, was being very comfortable the whole time.
