I would like to know if there any advantages in using 23mm rear tyre and 20mm front tyre or any other combinations.

I'd stick with 23's, unless you have a good reason to use something else. Good reasons might be:

*using a narrower tire in front for time trials, where the rim is narrower and you want to match the width for aerodynamics

*using wider tires when comfort becomes very important, especially on very rough roads

*using wider tires if you are carrying a lot of extra weight

*using narrow tires if you happen to be very light, like 120 pounds

In my experience, narrower tires pinch flat more often, have a little less grip, and require higher pressures. Higher pressure is not always good (more is better??). Higher pressures can make the bike uncomfortable, make the tires bounce across the pavement in turns instead of gripping, and this is after a point of very diminishing returns in rolling resistance.

What sort of roads do you have down under?

I ride the above f/b.

No noticeable in rolling resistance, I am 220 lbs, and the roads where I ride are awful - it makes the whole thing more comfortable. Also, the 25 seems to have a rounder profile (on cosmics anyway), which makes cornering nicer.

If you are lighter, I guess the same logic applies 20/23

I ride Vittoria Rubino Pros, FWIW.
