Only 1.27k feet of climbing, so flat to rolling, and the whole back half of that I pulled a flailing club mate as I was riding sweep that day. Never even thought about touching the small ring.

You might like the 52/36 mid-compact front with an 11-25 then.
You loose a tiny bit of top end and get about 7% lower gears on the low end.
