Hi kropa,
the Shapton Pros are excellent stones; I'd recommend them. I routinely finish my razors on a 12k Shapton. They have an advantage over many other synthetics in that they don't need soaking - they're essentially splash and go. I would however recommend lapping new ones on a flat tile with several sheets of wet and dry, say 320 and 600 grit using a pencil grid to determine when flatness has been achieved.
Interestingly, not a lot of honers on this forum use them as their primary stones; the Naniwa superstones are much more popular but they do need soaking and are possibly a bit more prone to dishing out. The Shaptons are quite hard and don't wear easily but they benefit from a trip over a DMT to remove swarf every now and again.
