Tom, it's true, the TS trigger sub 2# out of the box, mine is fully tuned to just over 1.5# with an 18# hammer spring; if I run a light hammer spring it's close to 1#, but it gets a little mushy. The TS has a unique trigger return mechanism which increases it's potential beyond the rest of the CZ75 patter pistols. The trigger return spring is much lighter and shaped differently and the U spring under the trigger bar is eliminated, as well as half the trigger bar.
So your SAO SP01 will simply never be as good as the TS can be, but to get the best out of that fire control system, the hammer hooks are very important, excuse the blurry picture, but this is the stock SP01 hammer, next to the stock Shadow hammer next to the comp hammer:
you can see the hooks get progressively shorter; the race hammer on my TS has very short hooks:
