Thanks for starting the nice ride report. We eagerly await your photos.
Based upon the riding you prefer, perhaps you would enjoy a 14T/46T, or 13T/42T sprocket combination.
I think it might be beneficial for you to choose your preferred counter shaft (C/S) sprocket, and then buy a spare sprocket carrier. Then you can easily switch between two sprocket carriers with different size sprockets for the rear wheel.
Swapping the sprocket carriers is easier than removing the C/S sprocket, and less troublesome/expensive than bending a lot of safety washers during the C/S sprocket changes.
