Nice Picture, I do need to get a good one posted. Have you tried any of the Yaqi doc razors/heads? I have seen some info that they made me the same exact head, just different companies. I won't know for sure until I receive them in the mail hopefully sometime soon.
Based on my personal inspection, the Yaqi and RazoRock doc heads are identical. I never gave them a head-to-head shave on the same handle, but I there is no reason for the heads to work differently. A RazoRock SS handle and that Yaqi shorty are very different!
Here is a Yaqi v PAA comparison shot. Not a lot of difference, but the very grippy PAA handle shades it to a win for me.
