Lv 31 is for Quilava so I suggest just holding off evolving to get it a little earlier.
I always liked this concept of holding off evolution to get acess to moves faster, but the balance needs to be better, you evolve at 14 so waiting to lv 27 just to get a slightly better move is stupid, at least make it 23.
