Welcome to SRP Swirv. Sounds like you've done your homework. Knowing what I know now, if I had it to do over again after 9 years, and most of the hones, I'd get a Chosera 1k for bevel setting, a Norton 4/8 for sharpening/finishing, a Naniwa 12k SS, and a diamond plate for flattening.

The Norton 1k is alright, but not nearly as fast/good as a Chosera 1k. The Norton flattening stone is alright too, but it will eventually need to be flattened as well, and is generally not truly flat to begin with.

Diamond plates are cost effective if you are going to be using your hones a lot. Otherwise wet/dry sandpaper is probably a good option. Of the diamond plates that I'm aware of, the DMT D8C (325) is decent and cheaper than the Atoma 400, which is what I'd get now if I didn't already have the DMT. There are other less expensive alternative plates but I have no experience with them myself.

SuperStones are great stones, and though I sold mine and bought the Choseras, there again, if I had it to do over I'd have kept the SS and would forego the Choseras. TBH, the Norton single grit 4, and 8K are my favorite synthetic stones. 1" thick and they don't 'move' while resting, so the only time they need to be lapped is from infrequent dishing due to use. The SS & Chosera (Specialty stones) are affected by humidity, temperature, and they need lapping every session ....... in my experience.

So that is my 2 bits ...........
