I ride 95% on the time on the 38T crank but realize I am hardly ever using a sprocket bigger than the 15T so I feel I am sometime under-exploiting my energy and could benefit from a bigger crank than 38T but shifting to 48T turns out quite tough pedaling......
Just shift down to the 21 or 24 when you shift to the big ring. There's no good reason to change the crank rings.
You have a really wide range in the sprockets, 11-32. It would probably be more efficient and convenient for you to tighten that range up and keep the triple as it is. Also cheaper.
