Guys,
Thanks for all the replies (I like that last one about powder coating!) I have raised the same medical concerns some of you folks have and will be sure to ask more pointed questions when we talk to another PS here pretty soon.
My wife is not out to get the "torpedo" or "casaba melon/porn star" look, just a "fuller" enhancement to a 36D. She is a 36C now, and although she looks good in the photo, much of it is due to the Victoria Secret whiz-bang pushup bra she is wearing. She had an awesome bustline prior to her having our son, but after the preganancy she breast fed. In addition, she has lost 60 lbs. since our son's birth, and the result is a case of (in her words) "the dangling sisters." Yes, I have tried reassurance and so forth, but I can tell that despite how good her lower body looks it has affected her self confidence.
In our discussions with the PS, we learned that because of her weight loss and so on the skin has only so much elasticity, so she can't really acheive the "Pam Anderson" or "super perky 18-year old" look. We were given samples of the various implants (saline & silicone) and the PS figured the max he could go given the lift he'd be doing at the same time was about 10cm in diameter and 300-350 mg, for you medical types out there.
The big turn off to me was looking through the doctor's portfolio.
There wasn't ONE patient in the photos that wasn't severely overweight or flat out obese, so there were no "Before" and "After" photos on slim & fit patients like my wife to get a really good comparison. In all honesty, there were some Before & After photos that proved "You can't put tits on a pig" or, in a couple of cases, a buffalo.
