Pasted strops will convex the edge slightly, making for much more work on the next stone to get back to the apex. If you want to use abrasives like that, you need to use balsa or some fine grained wood like pine instead of a cloth strop. Point being you won't be convexing the edge so much.
I've found you just have to work on the higher grit stone longer.
