I too was wanting to get the cohesive gel implants but I decided not to. In the US, they are only allowed to place the tear-drop shaped implants and I wanted round implants. Additionally, you will have a longer scar to accomodate the implant. I read several research articles regarding the cohesive gel implants, and I know that there is far less information regarding their safety. There are some research articles linking the cohesive gel implants with increased lymphocyte production--which can also occur with silicone (i.e. leaking). I just think that less is know about the cohesive gel implants (long-term sustainability, cracking issues, rotation concerns especially with the tear drop) which made me shy away from them.
Also, keep in mind that a specific size is not always feasible because the plastic surgeon must work with the characteristics of your body (i.e. tissue stretch, size/shape of your natural breast, muscle and attachment concerns, etc.). I hope this helps. ;)
