I sent my gun to matt mink, angus hobdell also does it. depending on the hammer spring I can get my pull down to less than 3#. its not perfect but its way better than it was. I heard if you get rid of the firing pin block, it makes CZ triggers way better. It may also help to make the gun SAO. If you change out your hammer spring you should be able to lighten up the trigger quite a bit. the creep will still be there.
