With the 1200 grit stone your final Silicon Carbide Powder you would want to stop at is 8 Micron,it would really be a 9 Micron but they don't make a 9 Micron Silicon Carbide Powder in grit FEPA and if they do they are not listing on my conversion chart so 8 would be your final yes it doesn't have to be exact just close.
What you want to do is start with a F120 Sic then the next powder you would try and use would maybe be 2 to 3 grit's lower then your final powder you are supposed to stop at ,on my chart they don't list a lot,for example there is a J2000 but nothing is comparable to it in FEPA grit,so the final grit I would choose for the 1200 Venev would is a F800,they don't list a F650 or 700 but if they make Sic powder in those grit's that would even be a better choice,a F800 on my chart doesn't say the Micron size but it would be about a 6 to 6.5 or 7 Micron and they don't list a Jis rating for it either as I guess there is nothing to compare it to.
They may make an F650 or F700 but I don't have my set in front of me to confirm it not that it really matters.
But yes you are correct at stopping a 8 witch the math say's 9 not splitting hairs or anything,but what I would to do is start with the F120 first for the fastest removal of the resin as it can be slow going,then the next Sic you choose should be 2 grit's lower then the final grit your going to end with,you could also after using the F120 use 2 grit's of powder before ending at the final grit for a total of 4 powders being used because you may need the progression so as not to have mega deep grove's in the stone after ending at your final grit.
Also as a side note if you ever flatten a water stone with Sic powder it should always be finished with a Sic Powder that's at least 2 to 3 grit's lower then the stones rating to avoid the Sic powder getting lodged in the stone,the reason for this is because if the same or just one grit lower of Sic powder is used the particle's are the same size or to close the same size as the water stones particle's witch means the Sic can works it way between the stones particle's easier and get lodged in there and then rust,where as something that's 2 to 3 grit's lower is fine and 2 grit's lower is more then safe enough.
The Venev OCB resin stones are great and I'm just saying because I got to test them and I also got a OKC resin bond as well both in 1200 and is very much the same to me.
The difference is the OCB stones do not leave as deep of scratch's and also leave a much better scratch pattern as well,they were also having problems from what I seen on a Russian forum where people where looking at the 1200 normal resin bond under a microscope and saying that the diamonds were falling out,if you think about you can't whip up any old batch of whatever and just because holds a 10 12 or 13 Micron diamond in place and can't be torn out even if a 1000 pounds pressure is used on it to try and tear them out but that doesn't mean it's going to hold a 1 Micron very well at all and that is their problem from what I understand.
They also wanted to improve the scratch pattern the most as the diamonds were flying out of the stone like a man that has male pattern balding going on,if you look at my thread about my Benchmade 810 I explain what stones I used and I know it's not a perfect way to do it because I used my Metallic bond CBN stones and that was because it was a re-profile from 17 to 15 degree's on those knifes',the CBN stones leave bigger scratch's for sure,but as I'm clear about it I don't care about a perfect mirror polish I just want the performance that is the same and way less time and I didn't need to strop I just did.
I'm going to resharpen the first one I purchased as I got a second one right away after getting the first I liked it so much and now it needs a touch up,I also have on the way and show be here this week 2 Venev 800 OCB stones and I'm going to touch it up with the 800 first then the 1200 then take picture's before I move onto my Sigma Power 6 10 and 13K or maybe just use 2 of them and not 3,also the 800 OCB's I have coming I paid for and I paid the full price,if they were freebie's to review I'd say so and if I didn't like them even if they were free I'd be the first to complain about what I didn't like even if someone was going to get their girly panties in the worlds biggest knot.
Venev is also releasing a 400 grit OCB stone in 6 to 8 weeks but as new product release's go that could change like the wind but I think it will be close to that and then 2 of those will be heading my way.
As far as the price goes for the 1200 in the standard grit they are out of stock at gritomatic and don't show the normal price but every stone below that stone is in stock and they start 43 and go up to 47 usd and the OCB 800 is 48 and the 1200 is 51 witch really isn't that bigger of a price jump,Diemaker noted a while back that the OCB resin cost's more.
Also if you look at the normal stones what I like is they don't charge you more for the higher grit's at least that are in stock the 60 grit is the most money and there are some stupid's out there that when explained a 2 year can understand it still refuse to understand and listen to reason,it takes more diamond or CBN in a coarser grit to keep the particle ratio the same,that's also like the 10 Carat diamond paste I have the finer grit's are less money then the coarser grit's because to keep the particle ratio the same among all the grit's they have to add more in the coarser grit's or bigger Micron's.
They sell 3 different lines let's say of diamond paste's from the guy I deal with and this is not what they are called I'm just trying to make it simple Low Medium and High concentrations,I get the medium where the finest micron has 10 carat's per 40 gram container where the Low has 4 carat's in the same 40 gram bottle,and in the medium they stop at 60/40 witch has 40 carats to keep the particle ratio the same.
You won't be refreshing any of the Venev stones every 5 sharpening's or anything like that,so long as you don't go banana's and use all the pressure you got you could anywhere from 50 to 100 sharpening's out of them before touching them up and maybe only loose 1/2 to 1mm of the stones thickness,and it would most likely be more like a 1/4 mm or less just from sharpening and not from refreshing these ting like all Venev wear like iron.
Sorry being long winded about this but I know you are usually in the know on most thing's and to be honest you really shocked me that you weren't up on the Venev stone's more even if you don't own any,but then again Wowbagger that's what you get when you spend all of your spare time on your true passion and that's researching stropping because we all know your not just the strop master your the strop master ninja LOL,I know what your going to say so I'll say it for you and that is I should go screw myself correct.
Look at the OCB and the normal resin stones price wise it's not like they are charging 20 to 50 bucks more per stone the jump is reasonable if you ask me and from what I understand they are not charging more because they leave a better scratch pattern the new resin cost's more so it's a case of can't have your cake and eat it to.

This is the knife thread and the result's and it's much shorter,the scratch's in the blade are more from the Metallic CBN stones and are harder to clean up,I hope the by using the 800 and 1200 OCB stone that will clean them up to the point that when I use the Sigma Power stones no scratch's are almost none will remain just to confirm my thought's,I don't care about looking at myself in the edge for me it's all about the speed of cheating this way to get a polished edge performance in way less time once the blade has been re-profiled even if a few scratch's remain.
