Yes, natural, of course. I find the latigo the least desirable of the SRD strops. English bridle, Horsehide (I don't think that one's available any more), Naked. In that order. The rest are nice, but I liked those three best.

And let me firmly state that whilst draw, sound, and tactile feedback differ, performance is exactly the same. I am thoroughly grateful that a small but vocal group of people advertising "strop progressions" a few years back now seem to have moved on. Whichever SRD leather you buy, you will get good performance.
