I'm looking to standardize one go-to set of stones for my Hapstone rig. I like the ones I use now (Gritomatic double-sided diamond and some Shapton), but the heights vary a lot and I have to change my angle all the time.

It looks like the EP Matrix stones are getting great reviews. Has anyone used them as well as the Gritomatic CBNs?
 
I have used both, but freehand. Freehand, for the most part, I prefer gritomatics resin bonded stones. The binder is harder, without the slight elastic rubbery quality that the matrix stones have. Freehand sharpening is a bit more reliant on feel and feedback, and I find the stiffer binder easier to maintain my angle and produce a crisp clean apex.

That being said, the matrix stones are great performers, and the 2300 is still one of my favorite finishers on terms of edge quality. It polishes the bevel very well, and leaves a good amount of bite of the edge. If you're using a fixed system the matrix stones may actually be better for you. However, on a whole, for my style of sharpening, I prefer the gritomatic stones.
 
Here is a whole bunch of info. Maybe you've already seen the thread. Click on this :)
 
Scott Gunn a good reviewer in a facebook group called edge snobs compared the Venev OCB stones to the Matrix stones and he said the Venev do a better job polishing the edge but leave inconsistent scratch's on the edge where as the Matrix stones don't polish as well but leave a more consistent scratch pattern.

If I had to choose I think I'd go with the Venev just for the fact that the resin is harder witch means they are most likely going to last longer.

Another good water stone to add to your line up is a Suehiro G8 8K stone it's a Sic stone and man are they awesome.

I have a suehiro g8 stone too. Good stone. I typically only use it on non vanadium rich steels despite it using SiC instead of AlOx, but I'm about to start experimenting with it again as a finisher on those steels.

There was a scienceofsharp blog recently that suggested using non diamond/cbn as a finisher to grind away a bit of the steel matrix to expose the carbides on the edge without smoothing them out, resulting in more edge aggression. This may be counteracted by stropping with a diamond compound, so I've been looking for a good quality AlOx or SiC stropping compounds to complement this technique.
 
I often use water stones after diamond stones,I just jump right onto water stones after I decide what grit of diamond or CBN I want to stop at.

I find all steels that have had diamonds and CBN used on the benefit from water stones as well,I haven't tried the Suehiro Dual stones yet but I want to,the Cerax and Rika 5K are great and the Sigma Power Select 2 6 10 and 13K are great,with Suehiro I find generally anything make is a really good stone.

I like the Chosera stones but they are not my go to stones and that's mainly because I have a lot steels that have lot's of Vanadium in them or else I'd use them from start to finish.
