I am pretty indecisive with my favorites. I don't really have a specific top 10 order.
The bulldog owner microbadge is of my 2 year old English bulldog Freydis, I also have a 3 year old named Otto, but he is all white and I thought that Freydis would make a better microbadge. (Freydis is now 9 and Otto has passed on.)
The helicopter microbadge is of an Enstrom F28f, the model that I trained on.
