What adjustable has the smallest head?

[Greatgoo]

I'm thinking about getting a adjustable DE razor but I usually like thinner heads because I find them to be better for those hard to reach places. Which one fits the bill?

Thanks for the insight!

I have tried most of the Gillettes and the Progress, and of what I have used the Slim is the smallest. It is also my favorite.

i'd probably go with either a slim or a black beauty

I have a slim, FB, and two Mergresses. I find that the Mergress (Progress) has the smallest head and for me the easiest to shave my mustache area. However, all of them are terrific.
