The fact that the decision to approve of candidate C is not easy makes you effectively a swing voter; the chance that you do or don't vote for them is reflective of your approval of them. Either way it doesn't incentivize dishonesty, and it doesn't cause weird squeeze-outs of the middle candidate the way IRV does. I can see how that's less clear cut to a voter, though.
