Another in a long line of newbie ???'s.

I've got Tony's 4 sided paddle strop and one of his #2 hanging strops (well, they aren't Tony's anymore, I paid him!). I like the way the 4 sided paddle is laid out with two somewhat rough surfaces, and two smooth surfaces (Tony, chime in if you want to properly explain what they are). Based on what I am reading and learning here, I feel that I also need a/some pasted strops. My thinking is to pick up a couple of Tony's "second" strops for using the pastes. A good way to go, or should I look on ebay for used strops?
