switching from round to gummy

Has anyone made this switch?  I am scheduled for this procedure and am now having some second thoughts.  My round implants show a lot of ripples-esp on the right prophy side.  I don't really like their shapes either-one is flat with dog ears and the other looks like it is on its side with a big divot.  Both sit far to the outside.  My PS suggested the natrelle 410 in a bigger size than I have now. I should say that my pockets were made for bigger rounds than I have.  I asked for smaller implants than planned for at the last minute after liking the size of my expanders.

So I am wondering now if I should just go with round in a bit bigger size.  I am worried that my pockets were made for round and that the gummies won't fit right.  PS says he will have to do pocket work for them.  Also worried about them shifting around and not having enough fullness to them.  When I hold both foobs and push them a bit in towards each other they look great and this is the look I want.  With the right bra I can almost make it happen but otherwise they are just really ugly and flat looking.

Has anyone made this switch?  are you happy?  What do you feel the difference is?  Any info on these gummies would be great!  I haven't had great luck on my board search.
