Nice work doc,

Now, what you may want to do (and this is where a handheld gauge comes in handy) is drop 5 lbs. front and rear, and see if that improves the ride quality without diminishing the rolling/handling of your bike. If you don't like it, put the 5 psi back in, or maybe bump it up a bit more and again, is it better worse? The more you play with it, the better chance you'll have of honing in on what works best for you.

Incidentally, a nicer tire won't necessarily have a higher psi rating. When choosing a tire, make sure that you figure out your budget, and then determine what characteristics are going to be important. You'll get a lot of opinions, but what works best for someone else, may be a nightmare for you. There are always trade-offs.
