I'm trying to determine what I would like to get to flatten my stones: A certified Granite and use Wet/Dry paper or a DMTd8c. I will probably at some time get both but for now I just want to get what I would end up liking best for now. I have mostly synthetic (more shapton glass than any) in my progression. I know that this is probably more of preference but what are some of the pro's and con's of each.

Unless I end up doing a restore from a blade with a totally square bevel in the near future, I really don't need any slurry on my Norton 4/8 or chosera 1k at this moment.
