welcome.
at first let me tell you sharpening straights is a different ( have seen couple times people joins and says they do have experience sharpening knifes but after couple days they come back and said have problems with razors).i have never meet person in life . i get this information from srp. You may be exception i don't know.Now 8000 hone should be good enough but questions is what you mean by 8000 grit? hone made in japan or in usa. there is differences between japan and usa grits. japan 8k will be lower 6k usa. this is has been discussed in the forum early too.
hope this information helps.
