It was funny to read that old thread, which is just about the time I joined TE. At that time, I had a triple with a 12-25. I now have a triple with a 12-28 and a compact double with a 34-34 mountain derailleur.
No sense in making it harder for myself as I age. Although, I've been trying to use the triple a bit more for harder hills (it has a couple less lower gear ratios) because I suspect the Madone I'll have on my trip to Portugal will have a 25.
