I ride lots. over 4000 miles this year and counting. I'm not fast, so take this with a grain of whatever.
My bike came with a 50-34 and 11-25. I swapped the 11-25 for a 13-27, so I gave up your tall gear! I only miss the 11 gear going down big hills. Really.
I don't think it will be a problem. You should (if you belong in 50+) be working on spin and not tall gears anyway.
BTW, you'll be loving that low end if you do much climbing!
