Having only used an English Bridle, I've been mentally building a list of things to look for/ask about when it's time to treat myself to a second strop. For me, the degree of twist along the length when taut and rate of build-up on the finish are becoming more important factors. I always thought a fast/light draw might be the best happy medium because you can always slow down if you like, now I'm not so sure. The variety of steel types makes a big difference too.
