Chang,
I am new to the Razor Edge System too. At first, I had the same results you describe. The fine stone was smoothing down the burr but leaving a rough edge that wouldn't push cut. Now that I have used the fine stone for some time, it has become increasingly fine, and will really polish an edge. So just stick with it.
BTW- I learned how to sharpen on the Lansky but found after I got proficient that the stones sucked. Specifically, the extra coarse clogs up quickly and won't cut at all. I have a 710 coming back to me from BM- does the diamond extra coarse work much better? The recurve stymies the benchstone as you know.
One more question in case anyone is still listening. How does one true a benchstone after it dishes out? That may be a distant problem but I have rounded the edges a bit which makes sharpening the beginning of a blade difficult.
