If you only own 1 strop then none. You need a naked strop without abrasive for daily stropping.

The pasted strop should be a different piece of leather or balsa. You use it to refresh an edge, or to mellow a freshly honed blade. Generally even with light abrasives like chrome oxide you are aiming to do no more that 10 laps. If you are needing significantly more than that then the edge needs a stone refresh.

Chrome Oxide is the standard paste everyone uses it refreshes and leaves a nice edge.

Diamonds and CBN are more abrasive so you need the finest grade possible. If you want to use coarser grades in leu of honing then each grade needs it's own strop. Diamond stropping will never set a bevel but it could replace a 12K stone in a poor mans rotation.
