Like the others, I have never heard of this question.
I have heard trans men lament the fact that although we are giving circular areolas (like natal males), due to natural stretching of skin and such, they end up slanting. I have heard of attempts at cutting the areola differently so that the stretching results in a circular shape developing instead of the oblong product we end up with.
My point is, I think that it will come out oblong no matter what. I personally would be concerned about starting out with oblong if that is not the standard surgical approach. Of course, I am curious to know the name of your surgeon and also ask you if they have done many top surgeries?
Anyway, mine are oblong like the others, started out circular, and I am happy with them. Garramone does the size of a dime, not a nickel (standard in the surgical community), which I prefer.
I bet no matter what you choose, you will be happy with your chest in the end. It is hard not to be after what we started out with!
