What is your preference size over haptic? If it is size and you can't get it with silicone done, then you have no other choice.
If you go for smaller silicone, but in fact you was searching for size, then I will bet with you that you already plan the next operation trying to get what you want.
As you know there is an effect that most after surgery found out they went to small.
So safe yourself the time, pain and money and do what is more important to you.
