Good, not blindly following "higher authority", literally !!!
Shinko SR740/741 gave me best lap-times using 31/27psi, so you're in ball-park. Tread pattern also makes difference to tram-lining. Longitudinal grooves will grab and hold onto grooves in tarmac. Something like Dunlop Mutants would appear to resist that. It's certainly has good reviews for rain.
Recently best tyre deal yet!

Just put some on my VFR. Hopefully last more than 3-days track!
