you will find that what leather some like others don't, like so much of this sport. kangaroo is a fast leather, but feels a little funny to me, but I like the speed. buffalo leather isn't any better than cow or horse or even boar, its all in what you like. myself I,m more into shell than any thing, but a real nice piece of horse hide makes for a great strop too.

just experiment till you find what you like. or pick up some vintage ones and already have it made and ready to work with Tc
