If you're going single blade I'd go with a gentle aggressiveness head. I've bought this cheap ass chinese thing twice(I dropped my first one on stairs and it snapped) I bought it again and it is still as amazing as the first one. I can shave recklessly because it hasn't the aggressiveness of my other DE heads.

Oh, and I use Astra blades, if that matters at all.
I'm not hail corporating here, but this chineseium head works so freaking well.
I use Astra blade myself, they're like 17 bucks for 100 blades, next to free. I also got this cheap DE Chinese head and handle that shaves so gently is basically like a Mach 3. I literally can't seem to cut myself.

I recommend you try it, for 13 bucks canadian its nearly free. Won't be a big mistake if you don't like it.
