Hi Hun, I’m booked for the 29 March going for 500 cc/ 550 right as smaller , and i was Thinking whether it’s too big. I’m a 5.8 , 127 lbs, . It’s so funny how you panick and change your mind every second as at my first consultation was going for 450cc and had another consultation because I opted for 500 in the end. Good luck ( will post lots of photos pre & post op ).
