No weight to lose here, in decent shape, but I don't plan to ever buy a road bike without a triple crank unless I move to, say, Florida (which is unlikely as I like the mountains). I have a 52X11 which allows me to stay on a 50 km/h paceline on the flats if needed, and a 30X25 to go up a 20 km-long, 7% hill on the same day.

I also do not think triples should be "outgrown." I don't know how many times I have passed people on hills (men especially) who went on to say things like: "You could pass me because you have a triple!"

My father-in-law - an avid cyclist - could never get used to a triple. It does imply some different constraints with regards to shifting. But if you're accustomed to it already, embrace it!

Really, if there are substantial hills anywhere near you, do not feel like you have to change to a double. Unless you can climb any of those hills comfortably and enjoyably in your triple's middle chainring and NEVER use the 30-teether.
