If you just want a better shifting rear, put whatever you like there.
If you are happy with the size of your big chaniring and don't like shifting the front, just don't shift the front; then you will still have a bailout if you find yourself on a steep climb.
I agree that you should plot out whatever gear changes you contemplate to see how it compares to what you have and the gears you use.
Better shifting on the rear definitely. I don't really do any steep climbs and the ones I do are accomplished by simply moving though the rear gears. I don't have to come off the tall gear in the front.
