Good news all around, Komit!
I think you made the better choice in the long run for a 1K/2K coming straight off the WEPS 600. I did a microscope progression with the WEPS diamonds, then the WEPS ceramic 1200/1600 and jumped to the Chosera 5K, which I’m writing up on my blog (hopefully it will be ready in a couple of days..) Jumping straight from the 600 WEPS to the 2K Shapton can mask the deepest scratches of the 400, 200 and 100 WEPS diamonds if you used them, unless you spent more time making sure they were removed. When touching up in the future, you can then begin at the 2K.
Your next paddle can be a 5K/Balsa or leather strop 😉
BTW, the 2K Shapton will only ever produce a hazy finish at best – never a mirror. You can, however, get a slight mirror off the 2K Chosera if you work the mud enough.
That’s another difference that I’ve been noticing on the WEPS in particular (not so much on the full sized stones) – one of the advantages to the Choseras is that they do hold water, allowing them to stay wet longer during use, and using the mud as the stone dries is advantageous, whereas on the Shaptons the water does tend to drip off the stones quicker, and the resulting swarf on the stone hampers performance.
I also got my Diamond WEPS 800/1K- so I’ll be getting to those soon. B)
