This is actually the most rational use of a flip flop hub. Stick the 15 on the other side but leave the 16 on so you can change it around while riding or easily change it after a ride. Using both sides this way is a good way of fine tuning what gearing you want because eventually you'll reach a point when you realise you aren't changing the wheel around - that's often a good time to remove the superfluous cog.
