I played with lots of sprocket changes, mostly with the front. One tooth in the front is almost three at the back.
While it is easy to change sprockets, it's not something you want to do on the side of the road, although that would be best.
So, you have to make a compromise. What is most important to you vs what you have to give up. Only your opinion matters.
For The Dragon, a 16 tooth front would be nice. For the slab to get there, a 18 tooth would be better. 17 is perfect for the Blue Ridge parkway.
