Right now I'm thinking of replacing the 53t with a 50t chainring and swapping out the rear cassette to get rid of the 11t & 12t and add more gear ratios in the middle.
That sounds pretty close to my gearing, and I spend most of my time in my 39 ring. I have a 50/39/24 and a 14-25 on the back, although I might switch up to a 52 or 53 because I get pretty windy days here which means huge tailwinds.
If I was you and could get stuff localy or with cheap shipping, I might just get a new cassette first, then a 50T if you find your big ring is still too big. The change from a 53x11 to 53x13 or 14 is a pretty big jump.
