One of the reasons I like the terino 2 is because of the wings. Large and the XL have a 1 cm difference in the wing length. Which to me is a big difference. I am just wondering if I go with the XL if it will give me a way better defined jawline since the wings are longer. My ps is afraid since it is so wide that it might fold in on itself on the front of my chin. My goal is very prominent chin..and strong defined jaw. I am also having the submental lipo. my chin is .5" in back from my top lip.
