I would NOT go with the UltraSharp plates. I regret them. They are certainly high quality, but they don't list the micron ratings, only the grit. And the grit absolutely does not match up to what they say it is. They are definitely way coarser than the stated grit. I'm certainly not a sharpening expert, but just going by feel and pattern on the BH, my guess is
300=250, 600=300, 1200=600, 2200= 800, 3000=900.
It gets progressively more off the higher the grit. Before you say it, I used a pack of eBay BHs to break in the stones before I started on my bishops. I spent 20 minutes of pretty aggressive back-and-forth swipes on each stone. They're still very coarse. Even when you finish on the 3000 grit stone, there's no mirror finish even started. I used a piece of float glass after the 3k with 1000 grit sandpaper. And I pretty much instantly got a semi-mirror finish.
I didn't go with DMTs because I've read their quality has gone down dramatically the last couple of years.
I wanted a super coarse stone to get dings out and set bevels quickly, so I got the DMT Extra Extra coarse. It's perfect and I don't see any quality issues, at least on this one. Should have gone with DMTs for my regular stones.
Also, someone said sandpaper type doesn't matter. It ABSOLUTELY does. Aluminum Oxide sandpaper is useless on broadheads. That's sandpaper meant for wood. You need Silicon Carbide or Wet/Dry sandpaper.
