Rings and Cogs

Recently I have been thinking of chainring combos.  I am currently running a 172.5 Campagnolo Chorus 53/39 crank with a Centaur (?) 12-25 cassette.  Prior to that I was using a 11-23 cassette, which was no good for hills.  The 25 is moderately better, but not what I want.  Thanks to the late, great Sheldon Brown, I have put together a list of options.  Getting the 50/34 combo would be the easiest route to go, but I would prefer the 52/36 setup.  For Campy Chorus or Record cranks, that means stepping up the system to 11 speed.  Sure, no problem.  Chump change.
