Joe - you can't get any better than Shapton Glass stones for the Edge Pro. I use the 500, 1000 and 4000 stones that came with the EP Essentials set. It's a great combination. If you need to set a primary bevel on the EP, I would also get a Shapton Glass 220 or even the Nubatama Bamboo 150. I've set bevels with the 500 and even thinned an Artifex with it, and it's slow going for that type of metal removal. If you have a good bevel already set with the DMT (assuming you are consistent in holding an angle free-hand), the 500 is a great place to start in getting a sharp edge before moving on to the higher grits.
The EP will definitely show you any inconsistencies that you might have in setting a bevel free-hand
. I know it was an eye-opener for me, highlighting just how much more skill I need to develop sharpening free-hand.
The Shapton Glass stones can handle virtually any type of steel you can throw at them.
