My 'normal' progression is mostly synth: Shapton Pro 2k for a bevel setter, followed by SP 5k and 8k. Then koma followed by tomo on the finisher. I occasionally use a Mikawa nagura progression. I usually finish on thin slurry, when I begin finishing with fresh slurry, I can see the edge through the slurry until it darkens with swarf.
The heavy lifting stones are a Shapton Glass HR 500 and HR 1k, these get me to the 2k Pro.
Hope this helps!
Cheers, Steve
