Would trying a 12t sprocket be too big a jump to 92"?
If you already have a 12T sprocket, try it and see what happens. If you don't, then going bigger on the chainring is the way to go, it will be smoother and more efficient.
I don't have a 12t, but it's only a fiver, whereas a new chainring is £15. Also need to resolve the flipping-the-rear-wheel-to-give-65"-for-everyday-use-/-chain-length conundrum.
