I've been running 36psi in the Blockleys now for quite a while and it's a big improvement.
Somewhat counterintuitively, if you go up in small increments you might find that at about 30psi it stops improving and seems to lose feel but if you go sailing past that to 36 it improves markedly on the road and even higher on track.
With good front shocks this works very well, with standard shocks it is likely to be very harsh as the wheels get to move a fair old distance before the damping starts to try and reign in the motion.
