I find (and this is of course just my opinion), that different leathers produce different feels. Maybe it's true, maybe it's not.

I prefer the edge to an SRD Premium I to the SRD Roo. I prefer the poly webbing to the premium cotton. It's about how it feels A) in your hand when you strop, and B) on your face when you shave. I like having lots of strops to play around with, and to compare. I think it just really comes down to the draw and your personal preference. I like heavy draw strops when I'm stropping, so it's no surprise that I like the edges from heavy draw strops on my face.

My two cents.
