personal preference
the pressures that are recommended in the manual are really just guidelines. i would strongly suggest setting the bike up initially using the sag set-up procedure. because of the variables of bike/shock setup this is better than a stock air pressure recommendation. for example, i like to have my saddle on my blur as forward as the rails allow. this reduces my leverage over the shock. i run less air to get the same feel as a rider of the same weight with his saddle pushed back where the rider weight increases leverage.
i would do the sag set up with the help of a friend and then adjust air accordingly to suit your tastes.
