You probably won't get a razor as sharp as you want on the 8K. You may want to go to a finishing hone of some sort. My favorite at the moment - mostly because it is dead easy - is to use lapping film. Get a couple of sheets of 1 and .5 and cut them up in 2 1/2 wide strips. Put a spritz of water on a marble tile (1.85 at most places) and stroke the razor across them like you would your hone.
You are right, the Ti razors I've received from the factory are woeful - as in not sharp at all. Unfortunately, I've also had problems with them getting a truly keen edge at times but they can be made 'good enough'. AOS razors are not sharp from the box in my experience (two that I bought and five that I examined at an AOS in Las Vegas).
Your Ti will never be as sharp as the shavette. Straights are not as sharp as commercial blades. The technique you use makes up the difference - in spades. It is a journey - but a fun one.
Finally, since I think your post implies you haven't used a sharp straight before, I recommend you send the straight to a honing service and get it 'base lined' so you know what you are supposed to be shooting for. The film will get it there but you won't know you are there if you haven't seen it before - the shavette doesn't count.
