Like the others, My first good strop was Latigo. Prior to that, I had a very small buffed cowhide leather strop, Solingen I believe, good but small. I'm partial to SRD's strops. Huge selection, great prices, quality leather. The Premium 1 has a soft, buttery feel to it. Just the right amount of draw imho. The English Bridle has a bit more draw, and is a bit stiffer. I'd say in between the SRD premium 1 and the Latigo.

If I had to decide on 1 strop, It would be SRD's premium 1.
