That is exactly what I have done.
Having moved past all the stones to currently using the Shapton Glass stones, does not mean that the Choseras, or any other stone for that matter is bad,.....it just means that there are more suited stones available out there for my/your specific application.
In real life you really get what you pay for ultimately......although I daresay that any 30k stone is IMHO really not worth the expense related to the rest...
For the knives I own, my personal preference resorts to the Shapton GS stones.
Keeping in mind that most here are serious knife nuts and focus on ultimate results, while sharpening a knife with most stones (some just takes more effort than others) can be achieved to paper slicing ability, which wows the living sh*ts out of normal people not knowing any better.
I reckon we have "spoilt" ourselves......to the point of readily explosive self-dissatisfaction vs performance - a costly exercise at best (which we subconsciously attempt to justify via any means possible).
Fine tuning to personal preference will most always results in heated debates....
I say, that if it works for you - stick with it!
Using various grit sand paper on glass will get very, very good results....but do you want this....????
