43/10..ok so that's 4.3. A 15/46 would be a 3.07 ratio.
With 4.3:1 diffs that would be a nice 13.2:1 ratio. The pinions you have should be a nice range to play with. I would start w/ the 15 or 16, watch temps, and adjust from there. If the motor is hot and esc is cool, but a bigger pinion on, cool motor/hot esc, drop the gear ratio (smaller pinion.) If both are in a decent temp range, tweak gearing for more punch or top speed as desired.
