I'm similar in profile, 44, don't race, but do lot's of charity rides, centuries, and group rides. I love hills, but my old knees & joints don't, so I find spinning with a triple much easier on the body.
What I like about my triple is I know I can face nearly any hill, whether it's Mt. Washington or alpe d'huez, and I can pedal with confidence knowing I can thrive on hills versus suffer...
