6'1" 210lbs ThickSlick Sport 700x28

I rode them for a week at 80 psi.
Yesterday I rode both front and rear at 100.
Definitely a 'more lively' ride. Seemed faster but I don't know how much of that is psychological from the increased road feel.
Seemed like much less resistance going over rough road.
I did immediately notice that it was such easier to lock up the rear tire on downhills at the higher pressure.
Also noticed a better ride carrying 30lbs of groceries when I had 100 psi.

I've read on here where some people were running their rear FreedomSlick 700x28 at 120 (Max rating is 100).

I dodge potholes but I do have to ride on rough pavement and I carry bumps with my legs (I pay attention).
I have been reading a lot about "Tire Drop" etc..but a lot of the information out there is more about racing than street handling.

I'm going to try running the front 5-10 psi lower than the rear.
Any words of wisdom?
