I have 8, 12 and 24 kg. I like having the 24 for swings, snatch and rows, but I also wish I had something in between for some exercises like overhead press and curls.
Wouldn’t need them in 2 kg intervals just something in the middle but I’ve given up trying to find one. Sold out everywhere and sky high prices secondhand.
Now that you have a 24kg you can do the Secret Service Snatch Test. ;)
