I'm starting to get comfortable with the Takashima stone for my finishing stone. For now my sequence depending on the condition of the iron is: Set the bevel with either a 600 or a 1200 Atoma. Remove most of the diamond plate scratches and raise a small wire edge with a Washia then move on to the Jnats. Set up the Takashima finish stone with the Brick aka a Ikarashi. The slurry makes a big difference, it needs to be Goldilocks, not too much but also not too little.

Time I found the last couple of days and i've been beavering away on the rest of the chisels.
Here is one I just finished:
